Human Body Research Paper

March, 2015
The human body has six main systems and is a complex machine that is constantly working to keep us alive. Although each system has its own unique jobs to do, they synergize to keep us healthy and active.
The skeletal system is responsible for giving us support, structure, and protection and works together with the muscular system to move our body. Our muscles pull our bones, which allows us to move, jump, and run! The muscular system actually plays an important role in delivering oxygen to our body’s cells. Without the heart, one of our most important muscles, blood wouldn’t be able to travel around our body! Luckily for us, the blood travels through our lungs, where it drops off carbon dioxide and picks up oxygen that our cells are craving. Speaking of craving, did you ever know that the main purpose of our digestive system isn’t just to digest food? It’s job is actually to take nutrients and water out of what we eat and drink and then deliver it to the circulatory system where it gets delivered to the cells in our body. But none of these systems would work without the direction of our nervous system!
Now let’s get right into it with the skeletal system, where you’ll learn how our bones help us move and protect our organs.
Skeletal System: Skeletal System Body Paragraph 1:
Introduction:The skeletal system has several important jobs to do in our body. It is responsible for creating blood cells, providing our body with support and structure, and enabling us to move. We have several bones that are responsible for protecting our organs like the ribs protect our heart and lungs, and the skull protects our brain! Bones cannot move unless joined together at joints. Ligaments connect our bones together and cartilage prevents them from rubbing together which would be painful! We are so lucky to have strong, powerful, yet moveable bones in our body!
The bones in our body are made up of four distinct layers. Each of these layers has important responsibilities and are vital to our day-to-day life. The outer layer of bone is called compact bone. Compact bone is solid throughout and enables our body to be supported. Compact bone is so dense that surgeon’s need to use a saw to cut through it. The next layer of bone is called spongy bone and it is lightweight and porous, which prevents our bones from getting too heavy, but still be strong. It makes up about 20% of our skeleton, and it’s found mostly in long bones, joints, and in our spine. The center of many bones are filled with a gelatinous substance called bone marrow. Bone marrow is responsible for creating red blood cells and some of our white blood cells. Bone marrow also makes platelets for our circulatory system. In addition, bone marrow stores iron for when our body needs it. We have two different types of bone marrow: yellow and red. We are born with red marrow, but it slowly changes to yellow over time. Finally, the outermost part of bone is covered in periosteum, a thin, fibrous membrane that covers all bones. The membrane is responsible for helping to create new bone in children and does the same when adults sustain an injury. The periosteum is the site at which ligaments, tendons, and muscles attach to bone! It also contains the blood vessels that allow nutrients and oxygen to the get to the bones! Knowing the four layers of bones can help us to understand just how complex our human body really is!
Body Paragraph 2:
Introduction to joints:
Joints connect the hundreds of bones within the human body. There are many different types of joints and each of them have different responsibilities. There are four main types of joints including gliding or sliding, hinge, pivot, and ball and socket joints. Some types of joints have multiple locations throughout the body. The gliding joints are mainly located in the wrists, ankles, and spine of the human body. Gliding joints help the bones to slide past one another in many directions including up, down, on a diagonal, and side to side. This type of joint is also known as a plane or planar joint. The second type of joints are called hinge joints. They connect between two or more bones that can only stretch. The elbows and the knees are the biggest hinge joints in the body. The next type of joints are the pivot joints. Pivots joints help with twisting, stretching, and retraction. This joint can freely move. The final type of joints are the ball and socket joints.They help the bones to move in different directions and turn. These are located in the hips and the shoulders. Dislocation of these joints can happen when there is extreme force upon them. Cartilage and ligaments are very important parts of the body. Cartilage allows cushion in between bones. It is softer than a bone and is more flexible. Both cartilage and bones can be connected by ligaments. Ligaments are like a rubber band because they are short tough and stretchy. Without joints in our body and ligaments to connect them we would not be able to move, turn, or flex.
Conclusion: As you can see the skeletal system many important jobs to do. It allows us to stand straight up, move around and protect our most important organs. However the skeletal system can't move our body by itself. It needs the help of the muscular system as well.
Muscular System:
The Muscular system is responsible for many things in the human body. This system is responsible for allowing us to move. All types of muscle help with the motion of our body. The types are Smooth muscles which are involuntary and found in the digestive system, Cardiac which are also involuntary are in the heart, and skeletal which are voluntary. Without these we couldn't do or regularly everyday stuff. These are also responsible for moving our joints with one motion and thats pulling. Groups of muscles work together to make the body do what it does. These two paragraph will take you through the body and show you how they work and where they are. This first paragraph will show you voluntary muscles.
This paragraph will show you how voluntary muscles work, the different kinds of them and where their located. Skeletal muscles are located all over the body. They are voluntary muscles which mean that you can control them. These are the muscles attached by tendons to bones. They are also referred to by striated muscles. The reason they are called that is that they are made up of fiber that has horizontal stripes on it. Muscles never push. They work together and pull in different directions. It can also be called retracting or tightening. While under tension the muscles they can shorten, turn bigger or remain the same size. Biceps and triceps are located in the upper and lower arm. These muscles work together with the elbow joint to move your arm. Tendons connect bones to muscle so they aren't loose around your bone. These tendons are like rubber bands. They are made of tough band of fiber. The next paragraph will show you the muscles that are so great that they control themselves. These are called involuntary muscles.
This paragraph will show you where involuntary muscles are located, what they do and how they work. These are called involuntary because they are the opposite of volantary muscles. You cannot control these muscles. Cardiac muscles are only found in the heart but they some of the most important. These are responsible for pumping our blood. These muscles are very strong and tough. These muscles work together with the circulatory system so when they contract it pumps blood to all parts of the body. These muscle almost never stops. This muscle pumps once a second for a whole humans life. Smooth muscles are found inside hollow organs. There responsibility in the esophagus is to contract to push the food down your throat. These are found mostly in the digestive system.
So in this page it showed you the main parts of the muscular system, how they work and where some of them are located. Muscular system is just as important as any other system. These muscles show how important it is to work together because they wouldn't be able to do any of the stuff that they do by themselves. They can't push so they work together. The next page will show you the main parts of the circulatory system. This is responsible to make the blood flow where its supposed to flow.
Circulatory System;
Intro: In this page you will learn the job of the circulatory system. This system is responsible for pumping blood to the body. Blood is responsible for transporting water and oxygen to the muscles. This also consists of veins, capillaries, and arteries. These are responsible for transporting blood through them. These connect to the heart and transport it. There are the two different types of blood, white blood cells and red blood cells. They both have different jobs. The right side of the heart is responsible for pumping blood to the lungs. In these three paragraphs you will learn about the heart, blood vessels and blood. Most of these things are located everywhere. The heart is located off to the left of the center point of the body and is split into four sections. The left and right ventricles and the left and right Atrium. The next paragraph is all about the different blood types. This will explain what they do where they're made and where they go.
Blood is one of the most important parts in our body and we can’t live without it. There are two types of blood, white blood cells and red blood cells. Blood transports water and oxygen to our muscles so they can grow strong and healthy. Red blood cells are created in the heart and sent off. They get sent all around the body to deliver the oxygen, water and nutrients to the body. White blood cells are created in the immune system and are like little army men in your body. Their job is to fight off illnesses. Platelets are all around your body. There job is to stop bleeding. These create a net that liquid can’t go threw and that stops the bleeding. If you didn’t have these anytime you cut yourself you would bleed to death. Plasma is like a water stream that carries the blood in suspension. This is a pale yellow liquid in your blood vessels. The next paragraph is all about the blood transporters. The blood vessels. These run all through your body and there's three types of them. Veins, capillaries and arteries.
Blood vessels are very important to our body. If we did not have any the blood would not move through our body. These have plasma inside of them to keep the blood cells in suspension. These lead all around the body. To our lungs, our muscles and our brain and much much more. Blood vessels are not only tubes that blood travels through but they also have layers of smooth muscles around them. Capillaries which are the smallest, are tiny blood vessels that go into veins. The walls are so thin that they allow objects to pass through them. When you get a cut, these are the blood vessels that you cut and they release the blood. Veins are responsible for carrying deoxygenated blood back from the muscles. The also connect with capillaries. These are different then arteries because arteries carry oxygen rich blood. Oxygen rich blood means that the majority of gas in the blood is oxygen. But there is still a bit of carbon dioxide. This paragraph was all about the things that transfer the blood but what's the next one about, the place that they get the blood from. The heart is split into four chambers and the next paragraph will show you what they do.
One of the most important parts of our body. The heart. This paragraph will talk all about what the heart does and how it work. The heart is responsible for pumping blood to our body. The right atrium is responsible for taking oxygen poor blood and shooting it to the lungs.. It is there where they pick up oxygen and then sent back to the right ventricle. Then sent to the left ventricle, then sent up to the left atrium and off to the body. It is really cool how the heart does all this all by itself. It is a long process to get blood of to the body. The heart is really like a team of four players that work together. Next is the conclusion which we will review what we learned in this page.
In this page you had learned about the circulatory system. This system is responsible for pumping blood to our muscles. You learned about the four chambers of the heart, blood vessels and blood. They all are part of one big team called the body. And they work together to make it work the way it should. The next page you will learn about the respiratory system. This system is responsible for our breathing. This consists of our lungs, oxygen and much much more.
Respiratory System:
Intro: In this page you will learn about how air enters, goes to our lungs and exits our body. It is split into two paragraphs how air enters our body and how air gets to our lungs. This system is called the respiratory system. In each system there is 6 to 7 parts. The lungs are the main parts of the respiratory system. This has the respiratory tree, the gas exchange and air gets sent and sent back to the nose and mouth. The next paragraph will tell you about how air enters our body.
1st Paragraph: In this paragraph you will learn about how air enters our body. Air is a big part to our body. It comes through our nasal passage. Then tiny air sacs exchange the
gases. When you breathe out then it releases the carbon dioxide and it leaves your body. Then you breathe in then oxygen which takes the place of the carbon dioxide. Then it repeats.The tiny air sacs are called alveoli. Which is one of the main parts of the gas exchange. Then you go down to the epiglottis. The epiglottis is responsible to stop liquids or solids from coming down the wrong pipe. It covers the esophagus that takes down the food and the larynx which is also commonly called the voice box that takes down air. The vocal cords that are inside the voice box are what make our voice. They make different vibrations that create our voice. When you grow they stretch and create your voice deeper. The voice box which contains the vocal cords is which air travels up through and vibrates and creates sounds. The trachea is the tube that connects the mouth and nose to the lungs. This is a airway which air travels. The next paragraph will tell you all about how the air travels to the lungs.
Paragraph 2: In this paragraph you will learn about how the air you breathe travels to your lungs. This paragraph has the key parts and words that are lungs, bronchial tube, bronchus, bronchioles, alveoli, and the gas exchange. First our lungs which are spongy air filled organs that are on both sides of our chest. The lung on the left side is a little bit smaller than the right one. The reason is that the heart is in the way and takes up some of the space. Bronchial tubes are part of the respiratory tree. Whih is in your lungs. They are like the the trunk of it and splits off into bronchi then to the bronchioles which branch off into alveoli. These are all part of how air enters our body. The alveoli is where the gas exchange occurs. The exchange of gases is where the carbon dioxide and oxygen switch when you breathe in and out. In the next paragraph which is the conclusion will tell you about the next system and go over what this one had in it.
Conclusion: In this paper you have learned all about the respiratory system. This system is all about transporting air. The next system is all about the digestive system. You will learn all about how the food you goes through your body.
Digestive System:
Intro: This page is all about the digestive system. The main job for this system is defecation. There is two ways to digest foods which will be in the first paragraph. They are mechanical and chemical digestion. Also included is almost all the organs that participate in digestion. It will go through where the food travels and how it ends up. It also has two main functions. It gets the nutrients that we need from the food we eat and get rid of waste. A interesting fact about the digestive system it doesn't get waste out of our body during your sleep. And now on to the first paragraph which is started off by talking about the mouth.
Body paragraph 1: The mouth is where the digestion starts. Two types of digestion occur in the mouth. Mechanical which is mostly done with the teeth. The teeth break down the food into little bits. Chemical digestion which has to do with saliva which has enzymes in it. Then breaks it down and then no matter what type of digestion you do it turns into a bolus. Then the bolus gets sent down the esophagus using peristalsis. A motion that pushes the bolus down past the epiglottis which covers the trachea while your eating and travels to the stomach. The stomach releases enzymes and swooshes around the food to digest it better. Then travels to the small intestine. It is full of capillaries which absorb about 90% of the nutrients from the food we eat. The villi in the intestines help get the nutrients.
Paragraph 2: The pancreas that is located deep in the abdomen is a long flat gland. It produces pancreatic enzymes. These help break down food. Now onto the Gallbladder and Liver. Gallbladder is really like a container. It holds bile which is a liquid produced by the liver. It holds it until later when it is released into the small intestine. The liver is a big part of metabolism and does lots of things to help the human body. One of the things it does is regulates glycogen storage. Bile is created in the liver. It is a dark yellow fluid. The large intestine connects to the end of the small intestine. It absorbs most of the water in the food you eat. Then it goes onto the Anus. It is the end opening of the rectum. It has two sphincters that are like fences. This is the end part of deification. The next paragraph is the conclusion. The conclusion will review the main parts of the digestive system.
Conclusion: In this page it has talked about the digestive system. It has mostly talked about the main organs in the system. In the next page it will talk about a system that has one of the most important organs in our body. It controls most of the voluntary movement in our body. The system is the nervous system. And the organ is the BRAIN!
Nervous System:
This system is the nervous system. This is one of the most important systems and contains one of the most important organs. This is the brain. Paragraphs go down by what happens next. If you thought the brain brain did all the work then this is what really happens. The first paragraph all about the brain. It has do a lot in the body to make us live. The brain makes the involuntary muscles do what they do without you. The brain is very interesting.
This paragraph is all about the Brain. The Brain controls most of our body and makes it do what is does. Our body would not work without the brain. The brain sends signals to body parts to make them move. Located in the most anterior part of the brain is the cerebrum. It contains the cerebral cortex. The cerebral cortex plays are important roll in consciousness. It is split in two by a fissure. The cerebellum is the closest part of the brain to the back of the skull. Its main job is to regulate the muscle activity. It also plays a big role in motor control. Which consists of motor neurons in the next paragraph. The medulla also called the medulla oblongata. It is located between the pons and the spinal cord. It is a part of the brain stem. This deals with involuntary movements. The brain wouldn't do anything without the main idea of the next paragraph. These are the nerves.
The nerves cant do the stuff they do without the brain and other parts that play a part. Nerves are a fiber or bundle of fibers that transmits impulses of sensation to the brain or spinal cord. Sensory nerves carry signals to the brain. Then stimuli respond to it. Motor nerves get the signal then respond to them with movement. They are directly or indirectly control of muscles. The spinal cord is a long tube like bundle of fiber and nerves. It is connected to the midulla. We need something to transmit the signal to the nerves and those are neurons. The next paragraph is all about how they do what they do and what they are.
A neuron is a big part of nerves and the nervous system. These are little cells that are like messengers to the the muscles. It sends information in two types. One is electric and one is chemical. A synapses is a part of our body that allows a neuron to pass through it to send a signal. Dendrites is the part that actually first receives the neuron. A axon usaully is what sends the signals away from the the synapses. Then is sent off to the body to be used. Next will be the conclusion what will go over the main idea.
This was the nervous system. The last system of them all in this paper. It plays a big role in everything that we do in our lives. The three paragraphs were all about the brain, nerves and neurons. They are the main parts of the nervous system and they all wok together to make our body work.
Conclusion to the Human Body Research Paper: As you can see, the human body is a complicated, unique machine that does so many important things. Not only does it help you live, but it also helps you move, think, breathe, feel, and communicate! Can you possibly imagine what life would be like if we were missing even one of these important systems? If not, maybe a few of these valuable concepts will help you understand better:
Now you have read all about our human body and how it works 24/7 for us. I hope that you learned a lot and that you can apply some of this information to your everyday life

The human body has six main systems and is a complex machine that is constantly working to keep us alive. Although each system has its own unique jobs to do, they synergize to keep us healthy and active.
The skeletal system is responsible for giving us support, structure, and protection and works together with the muscular system to move our body. Our muscles pull our bones, which allows us to move, jump, and run! The muscular system actually plays an important role in delivering oxygen to our body’s cells. Without the heart, one of our most important muscles, blood wouldn’t be able to travel around our body! Luckily for us, the blood travels through our lungs, where it drops off carbon dioxide and picks up oxygen that our cells are craving. Speaking of craving, did you ever know that the main purpose of our digestive system isn’t just to digest food? It’s job is actually to take nutrients and water out of what we eat and drink and then deliver it to the circulatory system where it gets delivered to the cells in our body. But none of these systems would work without the direction of our nervous system!
Now let’s get right into it with the skeletal system, where you’ll learn how our bones help us move and protect our organs.
Skeletal System: Skeletal System Body Paragraph 1:
Introduction:The skeletal system has several important jobs to do in our body. It is responsible for creating blood cells, providing our body with support and structure, and enabling us to move. We have several bones that are responsible for protecting our organs like the ribs protect our heart and lungs, and the skull protects our brain! Bones cannot move unless joined together at joints. Ligaments connect our bones together and cartilage prevents them from rubbing together which would be painful! We are so lucky to have strong, powerful, yet moveable bones in our body!
The bones in our body are made up of four distinct layers. Each of these layers has important responsibilities and are vital to our day-to-day life. The outer layer of bone is called compact bone. Compact bone is solid throughout and enables our body to be supported. Compact bone is so dense that surgeon’s need to use a saw to cut through it. The next layer of bone is called spongy bone and it is lightweight and porous, which prevents our bones from getting too heavy, but still be strong. It makes up about 20% of our skeleton, and it’s found mostly in long bones, joints, and in our spine. The center of many bones are filled with a gelatinous substance called bone marrow. Bone marrow is responsible for creating red blood cells and some of our white blood cells. Bone marrow also makes platelets for our circulatory system. In addition, bone marrow stores iron for when our body needs it. We have two different types of bone marrow: yellow and red. We are born with red marrow, but it slowly changes to yellow over time. Finally, the outermost part of bone is covered in periosteum, a thin, fibrous membrane that covers all bones. The membrane is responsible for helping to create new bone in children and does the same when adults sustain an injury. The periosteum is the site at which ligaments, tendons, and muscles attach to bone! It also contains the blood vessels that allow nutrients and oxygen to the get to the bones! Knowing the four layers of bones can help us to understand just how complex our human body really is!
Body Paragraph 2:
Introduction to joints:
Joints connect the hundreds of bones within the human body. There are many different types of joints and each of them have different responsibilities. There are four main types of joints including gliding or sliding, hinge, pivot, and ball and socket joints. Some types of joints have multiple locations throughout the body. The gliding joints are mainly located in the wrists, ankles, and spine of the human body. Gliding joints help the bones to slide past one another in many directions including up, down, on a diagonal, and side to side. This type of joint is also known as a plane or planar joint. The second type of joints are called hinge joints. They connect between two or more bones that can only stretch. The elbows and the knees are the biggest hinge joints in the body. The next type of joints are the pivot joints. Pivots joints help with twisting, stretching, and retraction. This joint can freely move. The final type of joints are the ball and socket joints.They help the bones to move in different directions and turn. These are located in the hips and the shoulders. Dislocation of these joints can happen when there is extreme force upon them. Cartilage and ligaments are very important parts of the body. Cartilage allows cushion in between bones. It is softer than a bone and is more flexible. Both cartilage and bones can be connected by ligaments. Ligaments are like a rubber band because they are short tough and stretchy. Without joints in our body and ligaments to connect them we would not be able to move, turn, or flex.
Conclusion: As you can see the skeletal system many important jobs to do. It allows us to stand straight up, move around and protect our most important organs. However the skeletal system can't move our body by itself. It needs the help of the muscular system as well.
Muscular System:
The Muscular system is responsible for many things in the human body. This system is responsible for allowing us to move. All types of muscle help with the motion of our body. The types are Smooth muscles which are involuntary and found in the digestive system, Cardiac which are also involuntary are in the heart, and skeletal which are voluntary. Without these we couldn't do or regularly everyday stuff. These are also responsible for moving our joints with one motion and thats pulling. Groups of muscles work together to make the body do what it does. These two paragraph will take you through the body and show you how they work and where they are. This first paragraph will show you voluntary muscles.
This paragraph will show you how voluntary muscles work, the different kinds of them and where their located. Skeletal muscles are located all over the body. They are voluntary muscles which mean that you can control them. These are the muscles attached by tendons to bones. They are also referred to by striated muscles. The reason they are called that is that they are made up of fiber that has horizontal stripes on it. Muscles never push. They work together and pull in different directions. It can also be called retracting or tightening. While under tension the muscles they can shorten, turn bigger or remain the same size. Biceps and triceps are located in the upper and lower arm. These muscles work together with the elbow joint to move your arm. Tendons connect bones to muscle so they aren't loose around your bone. These tendons are like rubber bands. They are made of tough band of fiber. The next paragraph will show you the muscles that are so great that they control themselves. These are called involuntary muscles.
This paragraph will show you where involuntary muscles are located, what they do and how they work. These are called involuntary because they are the opposite of volantary muscles. You cannot control these muscles. Cardiac muscles are only found in the heart but they some of the most important. These are responsible for pumping our blood. These muscles are very strong and tough. These muscles work together with the circulatory system so when they contract it pumps blood to all parts of the body. These muscle almost never stops. This muscle pumps once a second for a whole humans life. Smooth muscles are found inside hollow organs. There responsibility in the esophagus is to contract to push the food down your throat. These are found mostly in the digestive system.
So in this page it showed you the main parts of the muscular system, how they work and where some of them are located. Muscular system is just as important as any other system. These muscles show how important it is to work together because they wouldn't be able to do any of the stuff that they do by themselves. They can't push so they work together. The next page will show you the main parts of the circulatory system. This is responsible to make the blood flow where its supposed to flow.
Circulatory System;
Intro: In this page you will learn the job of the circulatory system. This system is responsible for pumping blood to the body. Blood is responsible for transporting water and oxygen to the muscles. This also consists of veins, capillaries, and arteries. These are responsible for transporting blood through them. These connect to the heart and transport it. There are the two different types of blood, white blood cells and red blood cells. They both have different jobs. The right side of the heart is responsible for pumping blood to the lungs. In these three paragraphs you will learn about the heart, blood vessels and blood. Most of these things are located everywhere. The heart is located off to the left of the center point of the body and is split into four sections. The left and right ventricles and the left and right Atrium. The next paragraph is all about the different blood types. This will explain what they do where they're made and where they go.
Blood is one of the most important parts in our body and we can’t live without it. There are two types of blood, white blood cells and red blood cells. Blood transports water and oxygen to our muscles so they can grow strong and healthy. Red blood cells are created in the heart and sent off. They get sent all around the body to deliver the oxygen, water and nutrients to the body. White blood cells are created in the immune system and are like little army men in your body. Their job is to fight off illnesses. Platelets are all around your body. There job is to stop bleeding. These create a net that liquid can’t go threw and that stops the bleeding. If you didn’t have these anytime you cut yourself you would bleed to death. Plasma is like a water stream that carries the blood in suspension. This is a pale yellow liquid in your blood vessels. The next paragraph is all about the blood transporters. The blood vessels. These run all through your body and there's three types of them. Veins, capillaries and arteries.
Blood vessels are very important to our body. If we did not have any the blood would not move through our body. These have plasma inside of them to keep the blood cells in suspension. These lead all around the body. To our lungs, our muscles and our brain and much much more. Blood vessels are not only tubes that blood travels through but they also have layers of smooth muscles around them. Capillaries which are the smallest, are tiny blood vessels that go into veins. The walls are so thin that they allow objects to pass through them. When you get a cut, these are the blood vessels that you cut and they release the blood. Veins are responsible for carrying deoxygenated blood back from the muscles. The also connect with capillaries. These are different then arteries because arteries carry oxygen rich blood. Oxygen rich blood means that the majority of gas in the blood is oxygen. But there is still a bit of carbon dioxide. This paragraph was all about the things that transfer the blood but what's the next one about, the place that they get the blood from. The heart is split into four chambers and the next paragraph will show you what they do.
One of the most important parts of our body. The heart. This paragraph will talk all about what the heart does and how it work. The heart is responsible for pumping blood to our body. The right atrium is responsible for taking oxygen poor blood and shooting it to the lungs.. It is there where they pick up oxygen and then sent back to the right ventricle. Then sent to the left ventricle, then sent up to the left atrium and off to the body. It is really cool how the heart does all this all by itself. It is a long process to get blood of to the body. The heart is really like a team of four players that work together. Next is the conclusion which we will review what we learned in this page.
In this page you had learned about the circulatory system. This system is responsible for pumping blood to our muscles. You learned about the four chambers of the heart, blood vessels and blood. They all are part of one big team called the body. And they work together to make it work the way it should. The next page you will learn about the respiratory system. This system is responsible for our breathing. This consists of our lungs, oxygen and much much more.
Respiratory System:
Intro: In this page you will learn about how air enters, goes to our lungs and exits our body. It is split into two paragraphs how air enters our body and how air gets to our lungs. This system is called the respiratory system. In each system there is 6 to 7 parts. The lungs are the main parts of the respiratory system. This has the respiratory tree, the gas exchange and air gets sent and sent back to the nose and mouth. The next paragraph will tell you about how air enters our body.
1st Paragraph: In this paragraph you will learn about how air enters our body. Air is a big part to our body. It comes through our nasal passage. Then tiny air sacs exchange the
gases. When you breathe out then it releases the carbon dioxide and it leaves your body. Then you breathe in then oxygen which takes the place of the carbon dioxide. Then it repeats.The tiny air sacs are called alveoli. Which is one of the main parts of the gas exchange. Then you go down to the epiglottis. The epiglottis is responsible to stop liquids or solids from coming down the wrong pipe. It covers the esophagus that takes down the food and the larynx which is also commonly called the voice box that takes down air. The vocal cords that are inside the voice box are what make our voice. They make different vibrations that create our voice. When you grow they stretch and create your voice deeper. The voice box which contains the vocal cords is which air travels up through and vibrates and creates sounds. The trachea is the tube that connects the mouth and nose to the lungs. This is a airway which air travels. The next paragraph will tell you all about how the air travels to the lungs.
Paragraph 2: In this paragraph you will learn about how the air you breathe travels to your lungs. This paragraph has the key parts and words that are lungs, bronchial tube, bronchus, bronchioles, alveoli, and the gas exchange. First our lungs which are spongy air filled organs that are on both sides of our chest. The lung on the left side is a little bit smaller than the right one. The reason is that the heart is in the way and takes up some of the space. Bronchial tubes are part of the respiratory tree. Whih is in your lungs. They are like the the trunk of it and splits off into bronchi then to the bronchioles which branch off into alveoli. These are all part of how air enters our body. The alveoli is where the gas exchange occurs. The exchange of gases is where the carbon dioxide and oxygen switch when you breathe in and out. In the next paragraph which is the conclusion will tell you about the next system and go over what this one had in it.
Conclusion: In this paper you have learned all about the respiratory system. This system is all about transporting air. The next system is all about the digestive system. You will learn all about how the food you goes through your body.
Digestive System:
Intro: This page is all about the digestive system. The main job for this system is defecation. There is two ways to digest foods which will be in the first paragraph. They are mechanical and chemical digestion. Also included is almost all the organs that participate in digestion. It will go through where the food travels and how it ends up. It also has two main functions. It gets the nutrients that we need from the food we eat and get rid of waste. A interesting fact about the digestive system it doesn't get waste out of our body during your sleep. And now on to the first paragraph which is started off by talking about the mouth.
Body paragraph 1: The mouth is where the digestion starts. Two types of digestion occur in the mouth. Mechanical which is mostly done with the teeth. The teeth break down the food into little bits. Chemical digestion which has to do with saliva which has enzymes in it. Then breaks it down and then no matter what type of digestion you do it turns into a bolus. Then the bolus gets sent down the esophagus using peristalsis. A motion that pushes the bolus down past the epiglottis which covers the trachea while your eating and travels to the stomach. The stomach releases enzymes and swooshes around the food to digest it better. Then travels to the small intestine. It is full of capillaries which absorb about 90% of the nutrients from the food we eat. The villi in the intestines help get the nutrients.
Paragraph 2: The pancreas that is located deep in the abdomen is a long flat gland. It produces pancreatic enzymes. These help break down food. Now onto the Gallbladder and Liver. Gallbladder is really like a container. It holds bile which is a liquid produced by the liver. It holds it until later when it is released into the small intestine. The liver is a big part of metabolism and does lots of things to help the human body. One of the things it does is regulates glycogen storage. Bile is created in the liver. It is a dark yellow fluid. The large intestine connects to the end of the small intestine. It absorbs most of the water in the food you eat. Then it goes onto the Anus. It is the end opening of the rectum. It has two sphincters that are like fences. This is the end part of deification. The next paragraph is the conclusion. The conclusion will review the main parts of the digestive system.
Conclusion: In this page it has talked about the digestive system. It has mostly talked about the main organs in the system. In the next page it will talk about a system that has one of the most important organs in our body. It controls most of the voluntary movement in our body. The system is the nervous system. And the organ is the BRAIN!
Nervous System:
This system is the nervous system. This is one of the most important systems and contains one of the most important organs. This is the brain. Paragraphs go down by what happens next. If you thought the brain brain did all the work then this is what really happens. The first paragraph all about the brain. It has do a lot in the body to make us live. The brain makes the involuntary muscles do what they do without you. The brain is very interesting.
This paragraph is all about the Brain. The Brain controls most of our body and makes it do what is does. Our body would not work without the brain. The brain sends signals to body parts to make them move. Located in the most anterior part of the brain is the cerebrum. It contains the cerebral cortex. The cerebral cortex plays are important roll in consciousness. It is split in two by a fissure. The cerebellum is the closest part of the brain to the back of the skull. Its main job is to regulate the muscle activity. It also plays a big role in motor control. Which consists of motor neurons in the next paragraph. The medulla also called the medulla oblongata. It is located between the pons and the spinal cord. It is a part of the brain stem. This deals with involuntary movements. The brain wouldn't do anything without the main idea of the next paragraph. These are the nerves.
The nerves cant do the stuff they do without the brain and other parts that play a part. Nerves are a fiber or bundle of fibers that transmits impulses of sensation to the brain or spinal cord. Sensory nerves carry signals to the brain. Then stimuli respond to it. Motor nerves get the signal then respond to them with movement. They are directly or indirectly control of muscles. The spinal cord is a long tube like bundle of fiber and nerves. It is connected to the midulla. We need something to transmit the signal to the nerves and those are neurons. The next paragraph is all about how they do what they do and what they are.
A neuron is a big part of nerves and the nervous system. These are little cells that are like messengers to the the muscles. It sends information in two types. One is electric and one is chemical. A synapses is a part of our body that allows a neuron to pass through it to send a signal. Dendrites is the part that actually first receives the neuron. A axon usaully is what sends the signals away from the the synapses. Then is sent off to the body to be used. Next will be the conclusion what will go over the main idea.
This was the nervous system. The last system of them all in this paper. It plays a big role in everything that we do in our lives. The three paragraphs were all about the brain, nerves and neurons. They are the main parts of the nervous system and they all wok together to make our body work.
Conclusion to the Human Body Research Paper: As you can see, the human body is a complicated, unique machine that does so many important things. Not only does it help you live, but it also helps you move, think, breathe, feel, and communicate! Can you possibly imagine what life would be like if we were missing even one of these important systems? If not, maybe a few of these valuable concepts will help you understand better:
- The bones in our body support and protect, while our muscles pull but never push!
- In addition, our blood delivers oxygen and nutrients to our cells, while the alveoli in our lungs exchange carbon dioxide for oxygen.
- Finally, our digestive system is responsible for extracting important nutrients and water from what we eat and drink, but we’d never be able to do any of these things without our amazing nervous system!
Now you have read all about our human body and how it works 24/7 for us. I hope that you learned a lot and that you can apply some of this information to your everyday life
