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.
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!
Body Paragraph 1:
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!
Skeletal System Paragraph 2:
There are six different joints in our body. The first one is called Cartilage. Cartilage is a flexible connective tissue that is found in various forms in the larynx and respiratory tract. Cartilage is stiffer and less flexible than a muscle. The second joint is called Ligaments. Ligaments can hold together two bones, cartilages, and can also hold together joints. Ligaments also are the tissue that connects to bones to from to a joint. Ligaments takes a very long time to heal if they break, sometimes it even involves a hospital trip. Then there are the Gliding or Sliding joints. These joints are a freely moving joints in which the articulations allow only gliding motions. Gliding and sliding joints also are synovial joint formed between
bones that meet at flat or nearly flat articular surfaces. The fourth joints are Hinge Joints. Hinge Joints are a type of Synovial Joint that has the ankle, elbow, and knee joints. The Hinge Joint also is made around two or more bones and the bone can only move along one axis to move. Another thing about Hinge Joints is that one of the simplest of Hinge Joints in our body is the Interphalangeal Joints found in the phalanges in fingers and toes. The fifth joint in our body is the Pivot Joint. The Pivot Joint is a certain type of the diarthrosis. Pivot Joints also allow rotation, protraction, retraction, flexion, extension, adduction, and abduction in our body.
One more thing about Pivot Joints is that in Pivot Joints, the axis of the convex articular surface is parallel to the longitudinal axis of bone. The last Joints in our body are the Ball and Socket Joints. The Ball and Socket Joints are natural or manufactured joints such as the hip joint. The Ball and Socket Joint also are a special type of synovial joints a type of joint that like highest freedom in motion in our body. Also the Ball and Socket Joints needs vasts amount of musculature to be able to move and structure such joints. Knowing there are six different types of joints in our body that all help us move in certain ways really helps us understand how these joints really are needed for our body to be able to move and structure!
Conclusion to Skeletal System
As you can see the skeletal system has many important jobs to do. It allows us to stand straight up, move are body around, and protect are most important organs. However, the skeletal system can’t move our body by itself. It needs our help of the muscular system yourself.
Muscular System
The Muscular system is a system made up of three main muscles that all help us move our bones. Every single one of these muscles help our body in some sort of way. for example the Voluntary Muscle is what controls our bones which is very important because without bones we would not be able to walk, or eat, or anything active at all! Then there is the Involuntary Muscles which are not controllable consciously. Last there is the Smooth Muscles which are found in the digestive system. Now that you know a little bit of each muscle read more to find out even more about these three muscles.
Body Paragraph 1: The first muscle of the muscular system is the Voluntary Muscle. The Voluntary Muscle are what controls our bones. The Voluntary Muscle usually helps you do things like run, ride a bike, eat, or any other thing that involves movement. The Voluntary Muscle is also known as the Skeletal System which is one of the three muscular system. These muscles include skeletal system which is what helps contract our bones.
Body Paragraph 2: The second Muscle in the muscular system is the Involuntary Muscles. The Involuntary Muscles are the muscles that are not controllable consciously. The Involuntary Muscle is found in places that are found in walls of internal organs such as the stomach and intestines, the bladder, blood vessels, and the heart. Both Smooth Muscle and Cardiac are very similar to Involuntary Muscles. Involuntary muscles include cardiac muscles which is why cardiac muscles are often called Involuntary Muscles. The cardiac muscles are found in the heart.
Body Paragraph 3:The last Muscle of the muscular system are Smooth Muscles. Smooth Muscles are found in the digestive system. These muscles are responsible for the contractility of hollow organs. These organs are, blood vessels, the gastrointestinal tract, the bladder, and the uterus.
Conclusion:
Knowing there are three different muscles now helps us understand better about what helps us move our bones and be able to structure!
Circulatory System
The Circulatory system has three main parts The Heart, The Blood, and The Blood Vessels.
Today we will learn about all three. Each has at least two things inside each part. For example the Heart has the four chambers in it.
Body Paragraph 1:
The first part of the Circulatory System is Blood. Blood is a reddish color liquid that circulates in the arteries and the veins. Blood also helps fight off infections along with being are transportation system. There are four main things in the Blood these things are, white blood cells, red blood cells, platelets, and plasma. White blood cells are the sentries. They work in the backbone of the immune system. These cells have a density from 4-11 billion liters of blood. Next are the red blood cells. Red blood cells are the most known blood cells. They carry oxygen throughout the circulatory system. If the flow of the oxygen stops then the body’s tissue dries up and gets dead. The third thing is platelets. Platelets are fragments in the cells of bone marrow. Platelets circle the around your blood for about ten days before they die in the spleen. The last thing in the Heart is plasma. Plasma consists about half of the blood volume in your body. It also is about ninety percent water and ten percent minerals, waste products, clotting factors, and hormones. The last thing about plasma is that without plasma blood cells would not be able to flow very well.
Body Paragraph 2:
The second part of the Circulatory System is Blood Vessels. Blood vessels are what passes blood, nutrients, hormones, and other substances, through our body. Blood vessels also have three main parts. The arteries,veins, and capillaries. Arteries make a smooth pathway for the blood to flow through though they do not let the blood go to the heart. When the pathways that the arteries make get damaged it can lead to death, namely heart attack, and stroke. Next are the veins. The veins flow blood to go to the heart. You can see a vein just by looking at your wrist the red and blue lines are called veins. Veins also are very flexible and unstable when there is no blood flowing through them. The last main part of Blood vessels are capillaries. Capillaries pass blood from the arteries to the veins. Capillaries are also very small and are about ten micrometers of a diameter long. Unlike veins you can not see your capillaries very well and especially can not see them my making a fist and looking at your wrist. The last thing I want to say about Capillaries is that they only allow water and ions into these pathways.
Body Paragraph 3:
The last and final part of the Circulatory System is one of the most important things in our body, the Heart.The heart is a large muscle continuously pumping blood throughout our body in the muscular contractions. Like a machinery if something happens to the heart it affects the whole body. The heart contains four chambers which are the Left Atrium, the Left Ventricle, the Right Atrium, and the Right Ventricle. Four chambers are the four chambers of the heart. The first chamber of the heart is the Left Atrium. The Left Atrium is the upper right of the heart. The lungs deliver oxygen to this chamber. The second chamber of the four chambers is the Left Ventricle. The Left Ventricle is responsible of pumping oxygenated blood through the body and brain. The third chamber of the four chambers is the Right Atrium. The Right Atrium does not allow the blood to go back to the body until it receives the oxygen its needs for the body tissues to survive. The last chamber of the four chambers is the Right Ventricle. The Right Ventricle is responsible for pumping blood to the lungs.
Conclusion: Now that we know about the three main parts of the Circulatory System, we can see how important it is. The circulatory system includes the heart which is the most important muscle in our body. The circulatory system also helps us pass blood through the the blood vessels and is a part of blood in general.
Respiratory System
There are three parts in the Respiratory System and two main ones. There is, how air enters the body, and how air moves in the lungs. Each one helps our body in many ways and is what helps the air get through and around our body/ respiratory system.
Body Paragraph 1:
The first part of the respiratory system is how air enters the body. Air enters the body by opening your mouth or breathing through your nose. It then goes down your trachea to the lungs, were the blood flows through the bloodstream. There is seven parts in how air enters the body. The first part is the Mouth. Air enters the body through the mouth or nose. The mouth helps start the process of the traveling to get the air to the lungs. The second part is the Nasal Passage. As the air goes through the nasal passage tiny hairs catch the particles and mucus catches all the germs before they can go to the lungs. The third part is the Epiglottis. The epiglottis is a flap in the throat that blocks the windpipe. It stops food/liquids from being swallowed. The fourth part is the Larynx. It is a funnel shape organ in the throat. It helps to protect the trachea and produce sound. The fifth part is the Vocal Cords. The vocal cords are located in the Larynx. They help produce sound when air goes through them. Vocal Cords don’t just help you speak they also help keep bad germs away from your lungs. The sixth part is the Voice Box. The voice box is located in the neck. It helps you speak and there is tissues helping support it. The final part is the Trachea. The trachea starts in the neck and goes to the chest. It is connected to the lungs. It helps air travels into the lungs.
Body Paragraph 2:
The second main part of the Respiratory system is how air moves in the lungs. You have to inhalation in some air to be able for it to get into the lungs. There are six main parts in this system. The first part are the Lungs. They provide the oxygen we need for our body to be able to have energy and do the things we do. The second part is the Bronchial Tube. The bronchial tube is a part of the respiratory tree. It helps get air to lungs so that we have the oxygen we need for our body to move and be healthy. The third part is the Bronchi. It is the lower end of the Bronchus and divides into two Bronchi. One Bronchi goes to the left lung and the other to the right. The Bronchi helps carry out and in air. The fourth part is the Bronchioles. On the end of the Bronchi is an even smaller part called the Bronchioles. They help transfer the air to the lungs and the bad air out. The fifth part is the Alveoli. After the Bronchioles is the Alveoli. It helps air get through the lungs. When air is passing through the Alveoli it blows up like a balloon. The last and final part is the Exchange of Gases. This helps unneeded or bad gases pass out of the body without harm. The Exchange of Gases is located in the lining of the lungs.
Conclusion:
Now that we know there are three main parts and six to seven main parts in those parts, it helps us to understand that the Respiratory System is what helps air flow through our body to give us the oxygen we need. Each body part helps us keep our lungs and other body parts in the Respiratory system safe and helps us be able to do some of the things we do.
Digestive System:
Introduction:
There is four main parts in the respiratory system. The mouth, the stomach, and the small intestines, and the large intestines. The digestive system is a group of organs. They help digest all of the food and water that goes into your body.
Body Paragraph 1:
The first main part of the digestive system is the mouth. The mouth has six main parts in it. The mouth helps air and food enter the body. The first main part in the mouth is the teeth. They help chew the food that goes into our body. The teeth also help produce speech and form the shape of your face. The second main part of the mouth is saliva. Saliva helps digest the food that goes into your body and also takes care of your oral health. Saliva is 99.5% Water, and 0.5% of electrolytes, mucus, glycoproteins, enzymes, and antibacterial compounds. The third main part of the mouth is the tongue. The tongue is a muscular organ in the mouth. It is covered with mucosa. The tongue helps swallow the food that goes into your body. It also helps with producing sound. The fourth main part of the mouth is the Bolus. Bolus is a mass of food at the chewing point of being able to swallow. Also the bolus pH is made out of alkaline because of saliva. The fifth main part of the mouth is the Esophagus. The Esophagus is a passway for all the chewed up food that goes to your stomach. The process of the food getting in and getting out is functioned by mucus and glands to keep the Esophagus moist enough for the food to travel. The last and final part of the mouth there is Peristalsis. Peristalsis are wave like muscles that helps move food around during the process of the parts of the digestive tract.
Paragraph 2:
The second main part of the Digestive System is the Stomach. The Stomach helps storage food. The Stomach has two main parts in it, the digestive juices, and the Chyme. Digestive Juices help with breaking down food. It includes, saliva, gastric juice, pancreatic juice, bile, and intestinal juice. Chyme digest food so it can go down the small intestine. Chyme has a very low pH balance because of bio. The third main part of the Digestive System is the Small Intestines. The Small intestines help provide about ninety percent of the food we need. The Small Intestines has five main parts in it. The first main part is the Villi. The Villi helps with absorbing food more affentiantly. They also put nutrients in the food and then pass it into the bloodstream. The second main part is the Pancreas. The Pancreas creates chemicals that helps break down blood sugar regulation and proper digestion. The third main part is the Pancreatic Enzymes. Pancreatic Enzymes help break down fat, proteins, and carbohydrates. The fourth main part is the Gallbladder and Liver. The Gallbladder is in a small little pouch that sits behind the liver. It stores bile produced by the liver. The fifth main part is Bile. The Bile is formed in the Liver. It helps digest fat. It is stored in the Gallbladder when you are eating. The final main part of the Digestive System is the Large Intestine. The Large Intestine is an organ responsible to collect waste that is not by the small intestine. There is one main part of the Large Intestine and that is the Anus. The Anus is a canal at the end of the digestive tract where the food comes out of.
Conclusion:
Now that we know about all six parts of the Digestive system hopefully you now know that the Digestive system helps you digest the food and water that you eat. I also hope that you know every part of every six main parts all leads up to how our food go’s in our mouth through the Esophagus down to the Stomach digest’s then to the Anus and then out. This is what we call the Digestive System.
Nervous System:
The Nervous System gives instructions to the other systems in your body. There are three main parts of the Nervous System. The Brain, the Nerves, the Neurons. All of three of these parts make a big difference on our body and help us react to surprises.
Part 1:
The first main part of the Nervous System is the Brain. The Brain is made up of Nerve Cells. These Nerve Cells help are Brain decide what action to take. There are three main parts in the Brain, they are, the Cerebrum, the Cerebellum, and the Medulla (Brainstem). The Cerebrum is the largest part if the Brain. It helps us with understanding behaviors with reactions. In the Cerebrum there are four main parts, the limbic system, basal ganglia,olfactory bulb, and cerebral cortex. The second main part of the Brain is the Cerebellum. The Cerebellum is the smallest portion of the Brain. It holds half the neurons in our Brain despite the size. The Cerebellum helps us with some of our movement, it also helps us with feedback and fine turning motor. The last main part of the Brain is the Medulla. The Medulla is located at the bottom of the Brainstem. This is a very critical part of the Brain, it helps with breathing and swallowing and basic motor functions.
Part 2: The second main part of the Nervous System is the Nerves. The Nerves have 3 different types of Nerves the Sensory Nerves, the Motor Nerves, and the Spinal Cord. Nerves are a bundle of white fiber in your body that impulses feelings that your body touch from the nerves to the brain. The first main part of the Nerves is the Sensory Nerves. Sensory Nerves look like an enclosed cable that is found in the Peripheral Nervous System. Sensory Nerves help transport the feelings that your hands or any other body parts feel to the brain. They also help deliver pain to the brain to tell your body that you have been hurt. The second main part of the Nerves is the Motor Nerves. These Nerves help you move. This means that every time you jump, or walk, or run, a Motor Nerve is involved. Motor Nerves also help you when you are exercising. You see Motor Nerves are made up of Motor Neurons, Motor Neurons help send signals to your muscle contractions. The last main part of the Nerves is the Spinal Cord. Have you ever felt the boney lumpy thing in your back. That is a Spinal Cord. A Spinal Cord is a long, thin, tube of nerves. The Spinal Cord protects the smaller spinal cord behind it, it also has three main purposes. One it helps for motor information. Two it helps for sensory information too. And three it helps with coordinating reflexes.
Part 3: The last and final part of the Nervous System is the Neurons. There are three main kinds of Neurons. They are Synapses, Dendrites, and Axons. Neurons are electrically excitable cell that goes through and transmits information through electrical and chemical ways. The first main Neuron is the Synapses. Synapses protect neurons from signaling with other chemical or electrical cells. The second main Neuron's is Dendrites. Dendrites are located in the dendritic tree. Dendrites are very important in helping out in synaptic inputs and determining what actions predictions are created by the neurons. The last main Neuron is the Axons. Axons are a long skinny projection of a nerve cell. An Axon helps keep away electrical impulses from your neuron’s cell body. What makes up Axons is Membrane. Membrane is what is on a Neuron Cell in animals and humans. When Axons interfere with signals while traveling through the body the axons have been identified to be the cause of degenerative neurologic disorders.
Conclusion: As you can see the Nervous System is one of the best systems because it controls our feelings and pain along with helping are brain figure out what is happening. I also feel that the Nervous System is also probably the 3rd most important system because we need Nerves in our lives otherwise things would not be easy.
Conclusion to all:
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.

Respiratory System
There are three parts in the Respiratory System and two main ones. There is, how air enters the body, and how air moves in the lungs. Each one helps our body in many ways and is what helps the air get through and around our body/ respiratory system.
Body Paragraph 1:
The first part of the respiratory system is how air enters the body. Air enters the body by opening your mouth or breathing through your nose. It then goes down your trachea to the lungs, were the blood flows through the bloodstream. There is seven parts in how air enters the body. The first part is the Mouth. Air enters the body through the mouth or nose. The mouth helps start the process of the traveling to get the air to the lungs. The second part is the Nasal Passage. As the air goes through the nasal passage tiny hairs catch the particles and mucus catches all the germs before they can go to the lungs. The third part is the Epiglottis. The epiglottis is a flap in the throat that blocks the windpipe. It stops food/liquids from being swallowed. The fourth part is the Larynx. It is a funnel shape organ in the throat. It helps to protect the trachea and produce sound. The fifth part is the Vocal Cords. The vocal cords are located in the Larynx. They help produce sound when air goes through them. Vocal Cords don’t just help you speak they also help keep bad germs away from your lungs. The sixth part is the Voice Box. The voice box is located in the neck. It helps you speak and there is tissues helping support it. The final part is the Trachea. The trachea starts in the neck and goes to the chest. It is connected to the lungs. It helps air travels into the lungs.
Body Paragraph 2:
The second main part of the Respiratory system is how air moves in the lungs. You have to inhalation in some air to be able for it to get into the lungs. There are six main parts in this system. The first part are the Lungs. They provide the oxygen we need for our body to be able to have energy and do the things we do. The second part is the Bronchial Tube. The bronchial tube is a part of the respiratory tree. It helps get air to lungs so that we have the oxygen we need for our body to move and be healthy. The third part is the Bronchi. It is the lower end of the Bronchus and divides into two Bronchi. One Bronchi goes to the left lung and the other to the right. The Bronchi helps carry out and in air. The fourth part is the Bronchioles. On the end of the Bronchi is an even smaller part called the Bronchioles. They help transfer the air to the lungs and the bad air out. The fifth part is the Alveoli. After the Bronchioles is the Alveoli. It helps air get through the lungs. When air is passing through the Alveoli it blows up like a balloon. The last and final part is the Exchange of Gases. This helps unneeded or bad gases pass out of the body without harm. The Exchange of Gases is located in the lining of the lungs.
Conclusion:
Now that we know there are three main parts and six to seven main parts in those parts, it helps us to understand that the Respiratory System is what helps air flow through our body to give us the oxygen we need. Each body part helps us keep our lungs and other body parts in the Respiratory system safe and helps us be able to do some of the things we do.
Digestive System:
Introduction:
There is four main parts in the respiratory system. The mouth, the stomach, and the small intestines, and the large intestines. The digestive system is a group of organs. They help digest all of the food and water that goes into your body.
Body Paragraph 1:
The first main part of the digestive system is the mouth. The mouth has six main parts in it. The mouth helps air and food enter the body. The first main part in the mouth is the teeth. They help chew the food that goes into our body. The teeth also help produce speech and form the shape of your face. The second main part of the mouth is saliva. Saliva helps digest the food that goes into your body and also takes care of your oral health. Saliva is 99.5% Water, and 0.5% of electrolytes, mucus, glycoproteins, enzymes, and antibacterial compounds. The third main part of the mouth is the tongue. The tongue is a muscular organ in the mouth. It is covered with mucosa. The tongue helps swallow the food that goes into your body. It also helps with producing sound. The fourth main part of the mouth is the Bolus. Bolus is a mass of food at the chewing point of being able to swallow. Also the bolus pH is made out of alkaline because of saliva. The fifth main part of the mouth is the Esophagus. The Esophagus is a passway for all the chewed up food that goes to your stomach. The process of the food getting in and getting out is functioned by mucus and glands to keep the Esophagus moist enough for the food to travel. The last and final part of the mouth there is Peristalsis. Peristalsis are wave like muscles that helps move food around during the process of the parts of the digestive tract.
Paragraph 2:
The second main part of the Digestive System is the Stomach. The Stomach helps storage food. The Stomach has two main parts in it, the digestive juices, and the Chyme. Digestive Juices help with breaking down food. It includes, saliva, gastric juice, pancreatic juice, bile, and intestinal juice. Chyme digest food so it can go down the small intestine. Chyme has a very low pH balance because of bio. The third main part of the Digestive System is the Small Intestines. The Small intestines help provide about ninety percent of the food we need. The Small Intestines has five main parts in it. The first main part is the Villi. The Villi helps with absorbing food more affentiantly. They also put nutrients in the food and then pass it into the bloodstream. The second main part is the Pancreas. The Pancreas creates chemicals that helps break down blood sugar regulation and proper digestion. The third main part is the Pancreatic Enzymes. Pancreatic Enzymes help break down fat, proteins, and carbohydrates. The fourth main part is the Gallbladder and Liver. The Gallbladder is in a small little pouch that sits behind the liver. It stores bile produced by the liver. The fifth main part is Bile. The Bile is formed in the Liver. It helps digest fat. It is stored in the Gallbladder when you are eating. The final main part of the Digestive System is the Large Intestine. The Large Intestine is an organ responsible to collect waste that is not by the small intestine. There is one main part of the Large Intestine and that is the Anus. The Anus is a canal at the end of the digestive tract where the food comes out of.
Conclusion:
Now that we know about all six parts of the Digestive system hopefully you now know that the Digestive system helps you digest the food and water that you eat. I also hope that you know every part of every six main parts all leads up to how our food go’s in our mouth through the Esophagus down to the Stomach digest’s then to the Anus and then out. This is what we call the Digestive System.
Nervous System:
The Nervous System gives instructions to the other systems in your body. There are three main parts of the Nervous System. The Brain, the Nerves, the Neurons. All of three of these parts make a big difference on our body and help us react to surprises.
Part 1:
The first main part of the Nervous System is the Brain. The Brain is made up of Nerve Cells. These Nerve Cells help are Brain decide what action to take. There are three main parts in the Brain, they are, the Cerebrum, the Cerebellum, and the Medulla (Brainstem). The Cerebrum is the largest part if the Brain. It helps us with understanding behaviors with reactions. In the Cerebrum there are four main parts, the limbic system, basal ganglia,olfactory bulb, and cerebral cortex. The second main part of the Brain is the Cerebellum. The Cerebellum is the smallest portion of the Brain. It holds half the neurons in our Brain despite the size. The Cerebellum helps us with some of our movement, it also helps us with feedback and fine turning motor. The last main part of the Brain is the Medulla. The Medulla is located at the bottom of the Brainstem. This is a very critical part of the Brain, it helps with breathing and swallowing and basic motor functions.
Part 2: The second main part of the Nervous System is the Nerves. The Nerves have 3 different types of Nerves the Sensory Nerves, the Motor Nerves, and the Spinal Cord. Nerves are a bundle of white fiber in your body that impulses feelings that your body touch from the nerves to the brain. The first main part of the Nerves is the Sensory Nerves. Sensory Nerves look like an enclosed cable that is found in the Peripheral Nervous System. Sensory Nerves help transport the feelings that your hands or any other body parts feel to the brain. They also help deliver pain to the brain to tell your body that you have been hurt. The second main part of the Nerves is the Motor Nerves. These Nerves help you move. This means that every time you jump, or walk, or run, a Motor Nerve is involved. Motor Nerves also help you when you are exercising. You see Motor Nerves are made up of Motor Neurons, Motor Neurons help send signals to your muscle contractions. The last main part of the Nerves is the Spinal Cord. Have you ever felt the boney lumpy thing in your back. That is a Spinal Cord. A Spinal Cord is a long, thin, tube of nerves. The Spinal Cord protects the smaller spinal cord behind it, it also has three main purposes. One it helps for motor information. Two it helps for sensory information too. And three it helps with coordinating reflexes.
Part 3: The last and final part of the Nervous System is the Neurons. There are three main kinds of Neurons. They are Synapses, Dendrites, and Axons. Neurons are electrically excitable cell that goes through and transmits information through electrical and chemical ways. The first main Neuron is the Synapses. Synapses protect neurons from signaling with other chemical or electrical cells. The second main Neuron's is Dendrites. Dendrites are located in the dendritic tree. Dendrites are very important in helping out in synaptic inputs and determining what actions predictions are created by the neurons. The last main Neuron is the Axons. Axons are a long skinny projection of a nerve cell. An Axon helps keep away electrical impulses from your neuron’s cell body. What makes up Axons is Membrane. Membrane is what is on a Neuron Cell in animals and humans. When Axons interfere with signals while traveling through the body the axons have been identified to be the cause of degenerative neurologic disorders.
Conclusion: As you can see the Nervous System is one of the best systems because it controls our feelings and pain along with helping are brain figure out what is happening. I also feel that the Nervous System is also probably the 3rd most important system because we need Nerves in our lives otherwise things would not be easy.
Conclusion to all:
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.
