Introduction To Human Body Research Paper:
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.v
Skeletal System: Skeletal System Body Paragraph 1: 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!
Body Paragraph 2: You just learned about all the layers of bones, now you will learn about all of the joints and how they help our body. A joint is a structure in the human or animal that two bones or more are combined together to make a joint. If we did not have joints we would not be able to do all the stuff we do regularly in an ordinary day. The first joint we will talk about is your cartilage. Cartilage isn’t that much of a bone. It just helps your bones and makes them smooth and easier to move around so it helps our body and we can move faster so we won’t be super slow. We would be super slow and couldn’t run in races or play sports because we would be really bad at all of them. We also have ligaments, there a short band of tough, flexible, fibrous tissue that help us move by connecting to or more bones together and holds the cartilage and bones together to form a joint. Without these we would have a bunch of different bones and no joints. A gliding joint, also known as a plane joint or planar joint, is a common type of synovial joint formed between bones that meet at flat or nearly flat articular surfaces. Without these we wouldn’t be able to move right and left or pretty much anywhere including diagonally. A hinge joint is a common class of synovial joint that includes the ankle, elbow, and knee joints and pretty much the whole lower body. We wouldn’t have barely any leg strength. There are only three pivot joints in the human body: one in the neck at the base of the skull and one in each elbow. Pivot joints help are head to move around and around. The shoulder and hip joints are the only ball-and-socket joints in the human body due to the need for great motion at the end of the body’s limbs and the vast amount of musculature needed to move and support such flexible joints. The ball and socket joints help you move your head round and round and your hips round and round. We couldn’t move our hips without ball and socket joints.
As you can see, the skeletal system has many important jobs to do. It allows us to stand straight up, move our body around, and protects our most important organs. However, the skeletal system can’t move our body by itself. It needs the help of our muscular system as well.
Muscular System: First you learned about the skeletal system and how it allows us to move, But you know what we can’t move without? Muscles! The first body paragraph I give you will be the voluntary muscles and those are the ones that our body can control, like our legs or brain. And then their are involuntary muscles, our body can not control those muscles. LIke some of our organs are examples. But, Don’t worry there are more examples to come!
Body Paragraph: The first thing that i'm going to talk about is the voluntary muscles. It allows us to move.There are two important terms to know when referring to location of muscles. The first is somatic,These Muscles are the main part of our body moving. Without these our body would probably not be able to move. These muscles can be controlled and are considered to be voluntary. An example of this would be the diaphragm. Most of Voluntary Muscles move your bones around. If you want to run, walk, ride a bike, or anything else that is pretty active, It is your voluntary muscles which move your arms, legs and body around. Our skeletal muscles are muscles that are connected to the skeleton to form part of the system that moves the limbs and other parts of the body.These muscles are responsible for relaxing when a person moves. Skeletal muscles are the muscles that we can sight and feel
through our skin. .Skeletal muscle relaxants are mainly acting things that work by bringing down the temper of skeletal muscle causing muscle to relax. Some skeletal muscles will not contract though. The tendons give extra support to help our muscles move are joints because the muscles can’t do it all by themselves! When a muscle contracts, it pulls on the tendon, which then pulls the bone to cause movement. The biceps and triceps make a good example of this.
Body Paragraph 2: We just learned about the muscles that we can control, now we are going to learn about the ones that we can’t. Involuntary muscles. Involuntary muscles are muscles that are not controllable,and instead contract due to unconscious impulses sent by the autonomic nervous system or definitely specialized cells or hormones.Both smooth muscle and cardiac muscle can be classified as involuntary muscles.Cardiac muscle (muscle in the heart ) is a muscle we can’t control striated muscle that is found in the walls and tissue foundation of the heart, specifically the myocardium. Smooth muscle is responsible for the
contractility of vain organs, such as blood vessels, the affecting the stomach and intestines tract, the bladder, or the uterus. Its structure is different greatly from that of skeletal muscle, although it can help equal force per cross-sectional area that is isometric to that of skeletal muscle. To relate functions of the the affecting the stomach and intestines tract learned in physiology, ... of smooth muscle in most of the digestive tract.
Now you know that we/you can not control your whole body, there are some muscles that control themselves and you have nothing to do with. After this in the next part we will be talking about the circulatory system. So Hopefully you keep reading on after this! Hahhaaha.
Circulatory System: Introduction: The Circulatory system is mostly made up of our blood and our heart, those are what the two body paragraphs are about. The first is on the blood. Blood flows around our body to help support our heart so we stay alive. And the heart’s job is to beat to keep us breathing and keep the blood moving so we can get oxygen to breath and we can’t live without breathing.
Body Paragraph 1: The first body paragraph will be about the blood. We can’t live without blood. It is a specialized liquid that supplies essential materials and nutrients, such as sugar, oxygen, and hormones to our cells, and carries waste or bad things away from those cells, this waste is eventually flushed out of the body in urine, feces, sweat, and lungs(carbon dioxide). Think of white blood cells as your immunity cells. In a way, they are continually at war. They flow through your bloodstream to fight viruses, bacteria, and other foreign invaders that threaten your health. When your body is in distress and a particular area is under attack
[war], white blood cells rush in to help vanish the harmful substance and prevent sickness. Red blood cells have the important job of carrying oxygen. Red blood cells have the key job of carrying oxygen. These tiny cells, which float in your bloodstream, begin their journey in the lungs, where they grab up oxygen from the air you breathe.a small colorless round-shaped cell fragment without a nucleus, found in large numbers in blood and involved in clotting.A tiny colorless round-shaped cell fragment without a nucleus, found in big numbers in blood and involved in clotting. Platelets are very small blood cells that help your body form clots to stop bleeding a lot. If one of your blood vessels gets damaged, it sends out signals that are picked up by platelets. The platelets then rush so fast to the site of damage and form a plug, or clot, to repair and fix the damage. Plasma is the clear, straw-colored liquid juice portion of blood that stays after red blood cells, white blood cells, platelets and other cellular components are removed. It is the single largest component of human blood, comprising about 55 percent of your blood and contains water, salts, enzymes, antibodies and other proteins. They help your body a lot. You definitely couldn’t live without Plasma.
Body Paragraph 2: Blood vessels form the living system of tubes that stream blood both to
and from the heart. All and everyone of cells in the body need oxygen and the vital nutrients found in blood to help the blood move. Not only do blood vessels carry oxygen and nutrients, but they also transport and carry carbon dioxide and waste products away from our cells so that we don’t get infected or sick. Any of the muscular-wall blocked tubes making part of the circulatory system by which blood (mainly that which has been oxygenated) is conveyed from the heart to every part of the body. A way to remember this is with roads rivers or railroad lines. any of the tubes making part of the bloodstream circulation system of the body, carrying in most cases oxygen-consumed blood toward the soul (heart). A Tiny in rock containing a bunch of minerals or ore and typically having an extensive course underground. Capillaries are little blood vessels that pass blood from the arteries into the veins. They are very tiny,
the largest being about 10 micrometers in diameter. Their walls are thin which allows materials to stream into them. Different types of capillaries live and perform different functions for the body. Primarily, however, they are able to gush the tissues of the body with needed oxygen and very important nutrients made by blood.
Body Paragraph 3: The blood provides your body with the oxygen and nutrients it needs. It also carries away waste. Your heart is sort of like a pump, it makes the blood flow, or two pumps in one. The right side of your heart receives blood gets oxygenated blood from the pulmonary veins, and pumps it into the left ventricle, via the mitral valve. The Left Ventricle receives the blood from the left atrium and contracts to push it to the atora. A ventricle is one of two very large chambers in the heart. They collect and expel blood given to an atrium towards the peripheral beds within the body and lungs. The left atrium is another oneof the four chambers in the heart.It recieves oxegyn blood from the pulmonary veins, and pumps it into the left ventricle. Atria make circulation easy primarily by allowing not interrupted venous flow to the heart, preventing the inertia of interrupted venous flow that would otherwise occur at each ventricular systole. The Right Atria is one of the four chambers in the heart. It receives oxygen from the inferior and the superior vena cava and blood from the digestive heart sinus(the outlet from the coronary circulation.) The right ventricle is divorced from the left ventricle by the septum. the ventricle's wall thickness for an adult is 4-5 mm.
Conclusion: You Just learned about blood, blood vessels, and the heart split into three body paragraphs. Next you will get to learn about the respiratory system and how it helps your body. Do you want to learn about it? If you do then keep reading to have more exciting information shared with you.
Respiratory System: You Just Learned about the Circulatory System. Now you are going to learn about the Respiratory System. The Respiratory system is about the skull part of the body like your lungs. The first body paragraph is going to be about how air enters the body. The second Body Paragraph is about how air moves in the lungs. Hope You want to keep reading it!
Body Paragraph 1: The Nose is one of the Main Parts of air entering the body. The Nose helps us smell and is also a Main part of the Respiratory System. Air comes into the body through the nose. The Mouth, also known as the oral cavity, helps food and air to enter the body. Most of the nose is concerned with filtering and providing a passage for air on its way to the lungs. Most of the nose is concerned with filtering and providing a passage for air on its way to the lungs. The Epiglottis is the flap of cartilage in your body that when your breathing, It closes the esophagus. When you have food and it’s coming down, The epiglottis closes the trachea. The symptoms of a bad Epiglottis are, Fever, sore throat, and breathing difficulties. The larynx is the hollow muscular organ forming an air passage to the lungs and holding the vocal cords in humans and other mammals; the voice box. Air passes in and out of the larynx each time the body inhales or exhales. This is what the voice box helps. This is how we talk, speak, sing, It can talk in very different voices too. The voice box is a part of the respiratory breathing part containing vocal cords which produce sound. The Trachea is the breathing tube of the part of the respiratory system. It is the tube that the air comes in and out of it.
Body Paragraph 2: This paragraph is about how air moves in the lungs. Every pair of organs that is in your rib cage, it has elastic sacs with branching passages into which air is drawn, so that oxygen can go pass into the blood and carbon dioxide can be removed. When a person breathes, the air goes through the trachea and passes through the bronchial tubes. Bronchus is definitely the main passageway to the lungs.When someone takes a breath through his/her nose or mouth, the air travels into the larynx. The bronchioles are not that helpful because they are not talked about too much. as often as the bronchi or alveoli, but they play an important role in your respiration. There are also several medical conditions that occur primarily in the bronchioles. Although there are many different types of alveoli in the body, the word alveoli is usually used to talk about small air sacs in the lungs of mammals. But they are used in humans also. These are also called pulmonary alveoli. These alveoli are located at the ends of the air passageways in the lungs. Exchange of gases is is when oxygen gets delivered from the bloodstream.
Conclusion: You just learned about how all the food and air gets into the body with the Skeletal System, Muscular System, Circulatory System, and Respiratory System. Now you are going to learn about how the food gets out of the body with the digestive system.
Digestive System: Right now you are about to learn about the digestive system. Ever wonder what the process of getting food in and out of the body is? Well if you do, keep reading so you can learn about what you have been waiting for.
Also known as the oral cavity, the mouth is the thing that allows food and nutrients and air to enter the body. The mouth contains many other organs - such as the teeth, tongue, epiglottis, and the ducts of the salivary glands - that work together to aid in the ingestion and digestion of food. It is also what helps you speak in the production of speech through the tongue.Watery liquid secreted into the mouth by glands, providing lubrication for chewing and swallowing, and aiding digestion. It is also found in each cheek on, on the bottom of the mouth, and under your jaw. The fleshy muscular organ in the mouth of a mammal, used for tasting, licking, swallowing, and (in humans) articulating speech. The bolus is a big mass substance that fo
rms into a ball and that is what goes down your esophagus. In digestion, a bolus (from Latin bolus, "ball") is a mass of food that (with animals that can chew) has been chewed at the point of swallowing. This bolus from an albatross has several ingested flotsam items, including monofilament from fishing nets and a discarded toothbrush, Tern Island, French Frigate Shoals. The esophagus is the tube that all the food that you eat goes down. When the patient is upright, the esophagus is usually between 25 to 30 centimeters long. The muscular layers that form the esophagus are pinched together at both ends by sphincter muscles, to prevent food or liquids leaking from the stomach back into the esophagus or mouth. Peristalsis are muscle contractions found in the digestive tract. These contractions are also very common in organs that link the kidney to the bladder. The Stomach is the internal organ in which the majority of the digestion of food occurs, being (in humans and many mammals) a pear-shaped enlargement of the alimentary canal linking the esophagus to the small intestine. Digestive Juices are Glands in the stomach lining. The glands in the stomach lining produce stomach acid and an enzyme that digests protein. Pancreas. The pancreas produces a juice containing several enzymes that break down carbohydrates, fats, and proteins in food. Acidic Fluid that passes from the stomach to the small intestine. Which has digestive juices and partly digested food. Part liquid and part mass, chyme does not resemble the actual food from
which it derives. This is because the stomach has long since broken the food down into its components, like proteins and fats. The small intestine is the one that lays between the stomach and Large intestine. The small intestine is a long, highly convoluted tube in the digestive system that absorbs about 90% of the nutrients from the food we eat. It is given the name “small intestine” because it is only 1 inch in diameter, making it less than half the
diameter of the large intestine. Villi increase the surface area of the intestine and are a part of the small intestine. And they also contain specialized cells that transport substances into the bloodstream. When food is broken down in the stomach, it forms a substance called
chyme, which is a slurry of nutrients. When that slurry passes into the small intestine, it comes into contact with the villi. The carbohydrates and proteins in the chyme enter the bloodstream passively via the vein and artery. A Pancrea a large gland behind the stomach that secretes digestive enzymes into the duodenum. Pancreatic Enzymes are pills/drugs that help you digest food. Certain medical problems can cause your pancreas to produce fewer enzymes than needed for digestion. The GallBladder is a small sac-shaped organ beneath the liver that the bile is stored in. The liver is a large lobed glandular organ in the abdomen of vertebrates, involved in many metabolic processes. The Bile is a greenish-brown fluid that aids digestion and is secreted by the liver and stored in the gallbladder. When people get a stomach flus they could vomit a yellow substance that is made of bile. The large intestine is the final section of the gastrointestinal tract that has the task of absorbing water and vitamins while converting digested food into feces. It is shorter than the small intestine but is super fat and large so that is why it is called the large intestine and the small intestine. The small intestine has to absorb a lot of water. It absorbs about 1 to 2 liters of dietary fluid each day. On top of that, another 6 to 7 liters of fluid is received by the small intestine daily as secretions from salivary glands, stomach, pancreas, liver and the small intestine itself. The Anus is the end of the digestive system and tract through which feces is expelled. It is about five inches long on average and is an extension of the rectum. It is only open during the expulsion of feces because it is usually kept closed by muscles, which can be relaxed at will.
Conclusion: That was the end of the digestive system. You learned about how food get into the body. And also how it gets out. The Next system you will learn about is going to be the last system in this Human Body Research Paper. The Nervous System. Hope you want to learn about it!
Nervous System:
Introduction Paragraph: You are going to learn about Two different Body Paragraphs Today. One of them being the Brain and the other being the nerves. I honestly think this will be my best one yet. The Brain is obviously the thing that helps you remember stuff, but you are going to be suprised by some of the facts that you see about all the parts of the Brain. And the nerves are the things that control and tell your Brain what to move and then your Brain tells the parts in your body and your muscles to move.
Body Paragraph 1: The Brain is the first body paragraph we are talking about. It is arguably the most magnificent part of the body. The brain tells us what decisions to make. And it tells our muscles when and where to move. The cerebrum develops the front part of the forebrain, it is the largest part of the brain. It has two large masses. The cerebellum is in the back of your brain. It accounts for about 11% of your brains total weight. It mainly has balance and posture. The medulla controls the midbrain of the brain. It is a part of the brain that attaches to the spinal cord. At the brainstem it is sent back and forth between the cerebrum or cerebellum and the body.
Body Paragraph 2: Now you are going to learn about the nerves. There are three different types of nerves. Sensory,Motor, and spinal nerves. The type of nerve you have is based on your neurons. Neurons are nerve cells that respond to outside stimuli by electrically and chemically signaling related cell networks within the central nervous system. Sensory nerves are vessels of the nervous system that carry signals towards the brain in response simuliti. Some of that might be environmental, as in changes in temperature, deliver cues about touch such as texture; involve an injury, as in feeling pain; or relate to the status of an internal organ. A motor nerve carries impulses from the center nervous system which tell the muscles to contract. All voluntary muscles are controlled by motor nerves. which means whenever a voluntary muscle moves, the motor nerve is involved. The Spinal Cord has 31 different pairs of spinal nerves. All though everyone thinks that our brain makes all the decisions, the spinal cords have been thought to have something to do with the decisions themselves. The spinal cords don’t have individual names, but they are separated into different groups. A neuron is a specialized cell that conducts information into chemical signals that trigger to some daily life activities. Neurons are the main building blocks of the Nervous System. synapses are structures that let neurons in the body communicate with each other. Dendrites are an important part of nerve cells. They pick up information from neurons close or neighbors and then they this information in the body. From this, it is passed along to the axon. The axon gives it to the dendrites of neighbor neutrons. The larger the axon the faster it can get information places. Some axons our covered with a substance that makes it an insulator.
Conclusion Paragraph: That Concludes The Human Body Research Paper that I just spent a long time writing for you. We Covered six systems. These include the Skeletal System, Muscular System, Circulatory System, Respiratory System,Digestive System, and Nervous System. I hope you enjoyed if you just read this ten page essay. I enjoyed writing it even though I had the hard times and the bad times. But I also had the good times. Like finishing each System.That felt so good. I worked really hard on it. Hope You liked it!
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.
