1Just about all there is to know about your body! By Audrey Peters The Human BodyJust about all there is to know about your body!By Audrey PetersIncluding:The Skeletal SystemThe Muscles of the BodyThe SkinThe Nervous SystemThe Digestive SystemThe Circulatory SystemThe Respiratory SystemANDThe HeartBackground:
3The Skeletal SystemYour body is made up of many bones, and they are all very important. Bones have two jobs. Bones like the backbone give the support that allows you to stand up instead of lying on the ground. Other bones protect the fragile, and sometimes soft insides of your body. The skull, a chain of connected bones protects your brain from damage. Your rib cage is a very important bone. It protects your heart and lungs from serious injury. What would you do without your bones?The skeletal system is very important to our bodies. Without it we wouldn’t be able support our bodies. Bones are a very important part of our bodies. When you were born you had over three hundred bones. As you get older your bones “fuse” together. When you grow to be an adult you will have two hundred and six bones. The skeletal system gives your body its shape and protects your organs.Healthy Hint: Drink plenty of milk (or have calcium, which is found in milk) each day to build strong bones.
6Muscles of the BodyMy ParagraphWithout muscles you wouldn’t be able to do a lot of things, such as lifting up things, talk, move your legs, and many more things you do everyday. About forty percent of your body weight is muscles. You wouldn’t even be able to breathe without them! Your body is made up of many muscles.Internet ParagraphMuscles help you smile, blink, breathe, move, and talk. The human body has over 630 muscles that help you move every day. Muscles usually work together so they can pull in different directions. They use chemical energy from food ,to do this. Muscles are made of cells that get smaller and then go back to their original size.Healthy Hint: eat foods containing protein, such as: meats and eggs, to build strong muscles.
9The Skin My Paragraph Internet Paragraph My Paragraph Internet ParagraphYour skin protects your bones and muscles. The skin holds your blood in ,and your bones. The only time your body may not hold in blood is when you have a cut or tear in your skin. It insulates you against all kinds of bumps and bangs. The skin helps protect your body , with it’s many layers.Your skin is soft, strong, water proof and self repairing. One way your could think about the skin is thinking of it as a large container. Without it, everything that it contains wouldn’t be together anymore. Your skin is the largest organ in your body, and helps protect you from many things.Healthy Hint: Wear sunscreen during the summer, and put lotion on to prevent dry skin.

11The Nervous System My Paragraph Internet Paragraph The nervous system is made up of the brain, the spinal cord, and the group of nerves that thread through your entire body. Your brain uses information it collects from your nerves to manage all of the actions and reactions . Without the nervous system you wouldn’t be able to exist! This is because the nerves and the brain work together to perform different actions.The nervous system helps you walk, paint, play sports, and many other things that you might do each day. The nervous system is made up of many nerves, your brain, and the spinal cord. Your brain takes information from your nerves. The nervous system is a very important part of your body.Healthy Hint: To keep your nervous system healthy, eat foods containing anti-oxidants, vitamins, and minerals, to keep your nervous system’s control center (the brain) healthy.
13The Digestive System My Paragraph Internet Paragraph Before cells in your body can use food , it has to be processed , by being digested, or broken down into nutrients. This is your digestive system’s job. It chews food into small pieces then exposes it to chemicals. These chemicals change complicated nutrients into simple ones. These are then taken in by your bloodstream. Any waste that has not been digested is removed.Once you chew a bite of food, chemicals in your saliva create chemical reactions. After you swallow, your muscles squeeze the wet mass of food down the esophagus. This happens in a muscle action called peristalsis. The valve in your stomach opens and the food lands in your stomach. Your stomach is full of half digested food that is being mixed with digestive chemicals. Food gets churned around and mixes with chemicals, breaking the food into even smaller pieces. Another valve opens and the mixture gets pushed into the small intestine. Chemicals and liquids from places such as the kidney and the pancreas break down the extras. The small intestine contains villi, they are like sponges and are able to absorb large amounts of nutrients from your food. After that, the nutrients will flow into your bloodstream. The extras that your body can not use are travel to the large intestine. It is wide and dry. The leftovers get smaller, harder, and drier as they are pushed through the tube. This is the place where water is taken out and is recycled back into your body. At the end of the large intestine the body waste is then eliminated out of your body.Healthy Hint: Eat fiber for a healthy digestive system, it can be found in cereals, nuts, beans, fruit, and raw vegetables.
15The Circulatory System My Paragraph Internet ParagraphThe Circulatory System is one of the most important systems in your body. It is made up of the heart, blood and blood vessels . Blood coming from the heart gives nutrients and oxygen to everything in the body. When the blood returns to the heart, it picks up waste products so your body can get rid of them. When you inhale, blood is pumped from the heart to the lungs, and oxygen gets mixed with blood. Then blood, mixed with oxygen, goes back to the heart where it is pumped through the arteries and capillaries .(a type of blood vessel.) The blood then travels to the whole body, giving oxygen to all the cells in the body. (including the bones skin and other organs.) At the end veins than carry the blood (with no more oxygen) back to the heart to do it all over again.The trillions of cells that make up your body’s tissues need supplies of food and oxygen, constantly, and to have their waste to be removed. Delivery and removal is provided by your circulatory system. Matter heading to or from cells are carried in blood. Pumped by your heart blood circulates around the body along in blood vessels. Your circulatory system also helps protect your body from infection and keeping your body temperature normal.Healthy Hint: Be careful not to eat a lot of fatty foods, or your arteries could get clogged.l
17The Respiratory System My Paragraph Internet ParagraphYour Respiratory System brings oxygen into your body and removes carbon dioxide. Your body cells use oxygen to release the energy they need to live. The energy is released in a process called respiration. This process also releases waste carbon dioxide, that has to be removed before it poisons your body. The respiratory system is made of the lungs and air passages that carry air to and from the lungs. It works by taking in air containing oxygen, and taking out air containing carbon dioxide. Your cells need a consistent supply of oxygen, so you don’t stop breathing.The cells in your body need oxygen. You wouldn’t be able to do many things. Without oxygen you would die. You get oxygen from breathing in air which your blood circulates all over your body. Your respiratory system takes in the oxygen and removes carbon dioxide from the air, so it is okay to breathe. Inside your body there are sacs that bring new oxygen from air that you have breathed to your bloodstream. They exchange it for waste products like carbon dioxide which the cells in your body have made but can not use.Healthy Hint: To keep your lungs healthy, do not EVER smoke.
19The Heart My Paragraph Internet Paragraph The heart has four parts the left ventricle the right ventricle the left atrium and the right atrium. Blood is pushed around the atrium into the ventricle on each side of the heart. Between them small valves open and close at each heartbeat to manage the flow of blood. The left side of the heart gets blood from the lungs where it has collected oxygen and pushes it all through the body. The right side of the heart gets blood after it takes oxygen around the body, then sends it back to the lungs for more oxygen.The heart pumps blood to the farthest parts of your body and back again, making sure that every cell gets oxygen, food and other supplies. Your heart about seventy times a minute at rest, but it speeds up when you exercise. Contractions of your heart are so powerful that it can pump your body’s entire blood volume in one minute. Your heart pumps without stopping for a break.Healthy Hint: Exercise at least three times a week to keep your heart healthy.Background:
21VocabularyVentricle-One of the two lower chambers on each side of the heartAtrium- One of the two upper chambers on each side of the heartBlood Cell-any of the elements of the blood, as white blood cells or red blood cellsPeristalsis- the wave of contraction and relaxation of a tubular muscular systemPancreas-a gland situated near the stomach that secrets a digestive fluid into the intestine through one or more ducts and also secrets the hormone insulinSac-A baglike structure in an animal, plant or fungus, as one containing fluidVilli-One of the many vascular projections of the small intestine
