Did you know that our bodies create about a gallon of mucus in just two days! I do. In fact, I know a lot of other interesting information about the human body, and YOU WILL TOO if you read my paper! Within this document, you will find six different body system essays including the muscular, skeletal, circulatory, respiratory, digestive, and nervous systems, which work together to operate our body. All these systems have different components, each with own unique functions that help to keep us alive. However, each system cannot operate alone - they need each other to be successful. For example, the nutrients gathered by the digestive system gets distributed throughout the body in the circulatory system!Over the previous 12 weeks, we gathered information, organized our thoughts, and paraphrased what trusted websites taught us about each system. We worked with responsibility partners and our papers definitely benefitted from the collaboration. Just like each human body system needs to rely on the other systems, we relied on each other to improve our writing and our process. The following is the result of our hard work...
Our skeletal system is made up of 206 bones. these bones work together to provide our body with support so that we can stand, help us to move so we can walk around, and protect our vital organs like our heart and our brain! Our bones even make and store blood cells for our circulatory system! Without our bones, we would be nothing more than a of skin, organs, and muscles on the floor. We wouldn’t be able to move and our organs wouldn’t be safe!
Our skeletal system is made up of 206 bones. these bones work together to provide our body with support so that we can stand, help us to move so we can walk around, and protect our vital organs like our heart and our brain! Our bones even make and store blood cells for our circulatory system! Without our bones, we would be nothing more than a of skin, organs, and muscles on the floor. We wouldn’t be able to move and our organs wouldn’t be safe!
Our bones are made up of many layers. These layers are important because we need our bones to strong, yet lightweight. In order to achieve this goal, the outside layer of bones is made up of solid, compact bone that makes our bones strong and dense. The next layer of bone is called cancellous (a.k.a. spongy bone). This layer allows our bones to be lightweight and transitions us from compact bone into bone marrow. Bone marrow is a thick and spongy section in the middle of bone where red and white blood cells are formed. Finally, our bones are all covered in a thin membrane called periosteum which is where our muscles attach to bones. So that is how bones are structured in order to keep our bodies strong, yet lightweight!
Although bones are extremely important, we wouldn’t be able to move without joints! Joints are places where two or more bones meet. There are several types of joints in our bodies, but we’ll just focus on four of them. The first type of joint is called a hinge joint. Just like the hinges on a door, they allow movement back and forth. We have hinge joints at our elbows and knees, and we even have them in our knuckles! Another type of joint is called a ball and socket joint. This is where one bone has a ball at the end of it and the other bone has a “baseball mitt” for the ball to sit in. Our shoulders and hips are examples of ball and socket joints. The third type of joint that we studied is called a gliding joint. Gliding joints are places where two or more bones meet and slide past each other. Our wrists and ankles are two examples of gliding joints. The last type of joint is called the pivot joint. A pivot joint works when one bone acts like a ring and the other bone sits inside the ring and rotates. Our neck is an example of a pivot joint because it can rotate around and move up and down. At each joint a soft, squishy material that can be found between bones which keep them from rubbing each other which would be painful. This material is called cartilage. Cartilage, which is bendable, can also be found in our ears and nose. But all of this wouldn’t be possible if it weren’t for ligaments holding our bones together at each joint. Ligaments are long stretchy
Bones definitely are an important part of the human body. They allow us to move, help provide structure and support, protect our important organs, and even make blood cells. Because bones are designed so well, they are strong, yet lightweight. Thanks to joints, ligaments, and cartilage, we are able to bend and move throughout our world. Finally, the muscles in our body attach to bones, giving us the power to actually move around!
The muscular system helps the human body move around and have fun. Let’s say you want to move your arms around, eat your favorite sandwich, our run, you use your muscles! There are many different types of muscles and they all serve different purposes. ( e.g movement, pumping blood, dilating your pupils). Some of these purposes are controlled by us, while others are controlled automatically by the muscle cell or the brain.
There are two types of categories of muscles in the human body: voluntary and involuntary. Voluntary muscles are muscles that we have control of. They are the muscles that control our body’s movements and are attached to bones. Skeletal muscles are the only type of voluntary muscle in our body. They pull on bones to cause us to move. Skeletal muscles never push, they only pull, and that’s why they are nearly always found in pairs. One example of this is the biceps and triceps that are located in our upper arms. When the biceps want to pull the lower arm up, they contract or shrink, while the triceps relax or expand. When the triceps want to pull the arm down, they contract while the biceps relax. This is an example of a pair of muscles working together to make movement. But those muscles wouldn’t be able to do any of this without tendons connecting them to the bones that they move! Tendons are flexible bands of tissue that blend into bones and enable them to move the bones that they were supposed to move. Although skeletal muscles are the only type of voluntary muscles, there are two different types of involuntary muscle!
Unlike voluntary muscles, involuntary muscles do stuff automatically without us knowing it. There are two examples of involuntary muscles. They are cardiac muscle and smooth muscle. Cardiac muscles are muscles only found in heart, and are responsible for pumping blood throughout our body. They work without us thinking about them, and the contract and relax throughout our entire lives. Smooth muscles are found inside many of our organs (e.g. intestines, esophagus, stomach, and bladder), and help move food through our body. Smooth muscles can be found in your eyes and your blood vessels. Smooth muscle cells may look look like one big cell, but are actually a bunch of smaller, smooth cells all grouped together (unlike the striated, skeletal cells). So clearly, there are many types of involuntary muscles in our body that do things we had no idea about. Including important tasks like pumping blood. and digesting food!
The muscular system is a powerful system that allows us to move, convert food into energy, and circulate blood throughout our body. Our muscles make up over half of our body weight and give and give our body tone and shape. In the next essay, learn how some of these muscles move blood throughout our body in order to deliver oxygen to all of our cells.
The circulatory system is made up of the heart, arteries, veins, and capillaries. Its job is to bring blood to your body parts. It is a very important system because we need blood pumped throughout our bodies to stay alive and healthy. Without it, we wouldn’t have enough oxygen to survive.
Blood is very important because it supplies essential nutrients to cells, such as amino acids, fatty acids, and glucose. There are two types of blood cells. They are white blood cells and red blood cells. White blood cells have antibodies which defend us from infections like a cold. It also has specialized cells called platelets which help the blood to clot when we are bleeding and makes scabs. Red blood cells have something called hemoglobin which is a protein that carries oxygen. They also remove carbon dioxide from your body and brings it to your lungs to be exhaled. Platelets are tiny cells that clot your blood when you are bleeding. Platelets make scabs to promote healing. Plasma is a yellowish liquid that is not related to the plasma in the earth. Plasma carries hormones, protein, and nutrients around your body. Blood is very important because it does many things for our bodies like carrying oxygen and helps protect us from disease.
Blood vessels transport blood throughout our body. There are three kind of blood vessels in your body: capillaries, arteries, and veins. Capillaries carry blood away from the body. They also carry nutrients, waste, and oxygen to tissues at the cellular level. The arteries also carry blood. They carry oxygenated blood away from the heart to the tissues. The veins are very important. They carry deoxygenated back to the heart to be oxygenated. The blood vessels are something we need to survive because they transport our blood for us.
The heart is the most supercalifragilisticexpialidocious part of your body. It acts like a pump, pumping out blood to your body. The right side of your heart receives blood. Then pumps it to the lungs. The left side of your heart does the opposite of what the right side does. The left side receives blood from the lungs and pumps it throughout the body. There are four chambers in your heart. They are the: left atrium, left ventricle, right atrium, and the right ventricle. Each chamber has its own job. The right atrium receives deoxygenated blood and then pumps it to the right ventricle. Then the right ventricle pumps the deoxygenated blood to the lungs. The left atrium receives oxygenated blood and pumps to the left ventricle. The left ventricle then pumps the oxygenated blood to the body. The heart is the most important part of the body.
The circulatory system is a very important system in our bodies. It pumps blood throughout our bodies, which keeps us alive. It also has the important job of carrying blood back to heart and to the lungs. Where would we be without it?
The respiratory system has any organs that are just tubes but we couldn’t live without them. They help us to breathe and they even oxygenate our blood. They are useless but important at the same time because they keep us alive.
The respiratory system is made up of the lungs and other organs that help you inhale oxygen, exhale carbon dioxide, and help you talk. Air enters the body by going through the nose or mouth, then into the trachea to the lungs. There are five steps for air to get to the lungs. The first step is entering through the nose or mouth. Then it goes through the nasal passage, were hairs catch unwanted particles and mucus catch germs before they get too far into the respiratory system. The next step is to go past the epiglottis. The epiglottis is a flap that allows air flow through to the larynx. The epiglottis also makes sure that food and drinks don’t go into the larynx by folding down over the windpipe. The larynx is tough, flexible segment of the respiratory system. It connects the pharynx to the trachea and is also the voice box. It contains vocal flaps that produce sound. The vocal flaps also known as vocal cords or voice reeds are made of thin infoldings of mucous membrane stretched horizontally from the back of the back of the throat to the front across the larynx. They vibrate modulating the airflow during phonation. The voice box also known as the larynx holds the vocal cords that produce sound. It is found between the pharynx and trachea. The fifth step is the trachea, half of the trachea is in the chest and the other half is the neck. The lower part of the trachea divides into two bronchi to carry air to the lungs. There are many steps for air to get to the lungs.
There are many origins with bronch in the name that help get air to the lungs. When you you breathe your diaphragm contracts and then moves downward to make breathe. Your chest cavity also expands so your lungs can fill up with air. It also gets rid of carbon dioxide. The lungs also oxygenate blood that goes all throughout the body. The first step in this is the bronchial tube. The bronchial tube lets air go in and out so that you can breathe, and they are found in the lungs. Next is the bronchus which lets air out of the lungs and there are two of them. The bronchus split at the end into smaller bronchi. The bronchiole is the passageway from the nose or mouth to aveliole. Finally it is the alveoli which give oxygen to the blood cells and take away carbon dioxide. There are many organs that get oxygen to our lungs and take away carbon dioxide.
The respiratory system has many organs that don’t do anything but are vital to our survival. They carry oxygen to our lungs and carry away carbon dioxide. They also oxygenate our blood that is goes throughout our body.
The digestive trail has many stops along the way. Food starts its journey in the mouth and ends its trip in the anus. There are many organs along the way that have different jobs, but they all have the same purpose.
The mouth is the very first part of the digestive system. Before you even take your first bite. The smell of your food triggers the the glands in your mouth and start producing saliva. When you finally take a bite the glands produce more saliva. The next step is your teeth! You have four incisors, two canines, and four molars on each jaw. Your incisors and canines are made to rip food away, and your molars are made for chewing your food. Then it is up to the solivia which is made up of electrolytes, mucus, antibacterial compounds, enzymes, and water. The enzymes amylase and ptyalin that are present in saliva break down starch in food which important for digestion. Your tongue is anchored in the hyoid bone. It is very important for when you want chew, swallow, and speak. Bolus is a mass of food that has been chewed to the of swallowing. The bolus then travels down the esophagus to the stomach for digestion.
The esophagus has one important goal! To carry food, liquids, and saliva to the stomach to be digested. Peristalsis is a wavy movement in the esophagus that helps carry food to the stomach. It is like the sides of the esophagus are doing the wave. This process sends the food down to the stomach for the next stage of digestion.
The stomach secretes acid and enzymes to help you digest food. Ridges in the stomach called rugae line the stomach and contrast periodically, churning food to enhance digestion. The digestive juices are secretions in the digestive tract that help break down food. The digestive juices are made up of saliva, gastric juice, pancreatic juice, intestinal juice, and bile. It is constantly produce in small amounts, but when food comes it comes in larger quantities. Chyme is a highly acidic, semi fluid that is made from the digestive juices and your food. If there were no chyme our bodies wouldn’t get the nutrients they need. Next, the journey continues in the small intestine.
The small intestine does 90% of our digestion. It is where our nutrients get absorbed into the bloodstream to be taken throughout the body. Villi are like an assistant for the small intestine. They help by increasing the area for the small intestine and absorb nutrients from food. Even though the small intestine works hard, there are other organs that help in the digestive process. One of these is the pancreas.
The pancreas is an organ that produces digestive juices. The juices help our bodies digest carbohydrates, fats, and proteins. The digestive juices then go into the small intestine, but they are neutralized first by the pancreatic juices.
The liver is another helper in the digestive system. Its main purpose is to process the nutrients in food. It also makes bile that help digest fat. The gallbladder is like a storage facility for the bile. When there is no food the bile go into the gallbladder to be stored. Then when fatty food comes the gallbladder squeezes the bile out. The bile’s job is to break down fats. The bile turn large fat droplets into small fat droplets that are easier to digest.After our food is digested in the small intestine, it moves into the large intestine. Most of the food has been digested already, so the main job of the large intestine is to absorb water from the chyme and prepare it to be expelled from our bodies. There are many kinds of bacteria in the large intestine that help break down food.
The anus and the rectum are the last stops on the digestive trail. The last section of the large intestine is called the rectum. At the end of the rectum is the anus, where feces leave the body.
Food takes an epic journey like no other through the digestive trail. All of the organs in this system work together to break down and digest food. Some organs seem to do nothing, and some seem to do a lot. But, they all work hard to make feces.
The brain is like the secretary of the whole body! It receives messages from nerves and then tells part of your body like your arm to move. It also controls your speech and thoughts! Your cerebrum is the big mushy looking part of the brain. It controls your actions like moving your leg and your thoughts. Without the cerebrum you wouldn’t be able dream! The cerebellum looks like two walnuts in the back of your head. The cerebellum’s job is is to receive information from the body. It also controls speech, posture, balance, and coordination. The cerebellum is very helpful when you want to walk because it makes sure you don’t fall. The brain stem is highway of the brain. It controls heart rate, swallowing, breathing, blood pressure, and conciseness. It controls if you sleepy or wide awake!
Nerves are like the mailman of the human body! They send electrical impulses to the brain so the brain can tell the muscles what to do. The next part is the sensory nerves. They turn external stimuli from organism's environment into electrical impulses. They also handle pain and emotion. Then we are on to motor nerves! The main job of motor nerves is carrying signals from the brain to the muscles. The spinal cord is made up of neural pathways. Messages are carried from the brain to the rest of the body by passing from neuron to neuron through junctions called synapses. A neuron is a special brain cell that carries information from the brain to other special cells in the body, like nerve cells or muscles. Most neurons have a cell body, an axon, and dendrites.
Dendrites are the segments of the neuron that receive information and allow the cell to do its job. An axon is a long, thin projection of a neuron that carries electrical impulses away from the cell. These parts are needed for synapses to occur. A synapse is a structure allows a neuron to pass an electrical signal to another neuron.
The five senses are a part of the nervous system, even though they may not seem like it. The five senses are: sight, hearing, taste, touch, and smell. Sight is the ability of our eyes to identify images we see. They do this through photoreceptors in the retina of each eye that make electrical nerve impulses for different colors. There are two types of photoreceptors: rods and cones. Rods are sensitive to light, but do not tell the difference between colors. Cones tell the difference between colors, but are not as sensitive to light. Hearing is mainly about vibration. Sound is vibrations going through the air. The vibrations go from the eardrum to a group of tiny bones in the inner ear, and that is how we hear. We use our taste buds on our tongues to taste foods. There are five basic tastes: sweet, bitter, sour, salty and umami. We feel things through our sense of touch. This happens when neural receptors in our skin are triggered by something around us. To smell, we have hundreds of smell receptors. It is the olfactory system’s job in the brain to sort out smells we smell.
In conclusion, the human body has many systems that each work hard to do specific jobs to benefit our bodies, but they also successfully to ensure our well-being. The skeletal system provides support, protection and structure while the muscular system allows us to move, breathe, and digest food. The circulatory system transports oxygen and nutrients to the cells of our body while getting rid of waste products and the respiratory system swaps out the oxygen and carbon dioxide. Finally, the digestive system converts food into energy while to make decisions and maintain memories. I appreciate the time you took to read these essays and hope that you learned something valuable. So the next time you move a muscle or take in a breath, I hope you’ll think about how impressive our human body really is!
Thank you…

These parts are needed for synapses to occur. A synapse is a structure allows a neuron to pass an electrical signal to another neuron.
The five senses are a part of the nervous system, even though they may not seem like it. The five senses are: sight, hearing, taste, touch, and smell. Sight is the ability of our eyes to identify images we see. They do this through photoreceptors in the retina of each eye that make electrical nerve impulses for different colors. There are two types of photoreceptors: rods and cones. Rods are sensitive to light, but do not tell the difference between colors. Cones tell the difference between colors, but are not as sensitive to light. Hearing is mainly about vibration. Sound is vibrations going through the air. The vibrations go from the eardrum to a group of tiny bones in the inner ear, and that is how we hear. We use our taste buds on our tongues to taste foods. There are five basic tastes: sweet, bitter, sour, salty and umami. We feel things through our sense of touch. This happens when neural receptors in our skin are triggered by something around us. To smell, we have hundreds of smell receptors. It is the olfactory system’s job in the brain to sort out smells we smell.
In conclusion, the human body has many systems that each work hard to do specific jobs to benefit our bodies, but they also successfully to ensure our well-being. The skeletal system provides support, protection and structure while the muscular system allows us to move, breathe, and digest food. The circulatory system transports oxygen and nutrients to the cells of our body while getting rid of waste products and the respiratory system swaps out the oxygen and carbon dioxide. Finally, the digestive system converts food into energy while to make decisions and maintain memories. I appreciate the time you took to read these essays and hope that you learned something valuable. So the next time you move a muscle or take in a breath, I hope you’ll think about how impressive our human body really is!
Thank you…
