background.jpg The Skeletal System ystem.htm The Skeletal System Your 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 system.htm serious injury. What would you do without your bones? The skeletal system is very

important to our bodies. Without it we wouldnt be able support our bodies. Bones are a very important part of our bodies. When you were born you had over three hundred bones.

The Bones 018.png Muscles of the Body ges/human-body-muscle-diagram.jpg Muscles of the Body My Paragraph Without muscles you wouldnt 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 wouldnt even be able to breathe without them! Your body is made up of many muscles. Internet Paragraph ges/human-body-muscle-diagram.jpg Muscles 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. Your Muscles Occipital Trapezius Deltoid Latissimus Dorsi Gluteus Maximus Biceps Triceps

Pectoralis Major Biceps Femoris Soleus Archilles Tendon gif The Skin The Skin My Paragraph Your 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 its many layers. http://www.f allingpixel.c om/product s/6592/mai ns/hand01.j pg Internet Paragraph Your skin is soft, strong, / skin.jpg&imgrefurl= water proof and self repairing. One way m/skin_biopsy/article.htm&usg your could think about the skin is thinking of it as a large container. Without it, everything that it contains wouldnt be together anymore. Your skin is the largest organ in your body,

and helps protect you from many things. 46.html Healthy Hint: Wear sunscreen during the summer, and put lotion on to prevent dry skin. The Nervous System files/nervous-system.jpg The Nervous System My Paragraph 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. 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 wouldnt be able to exist! This is because the nerves and the brain work together to perform different actions. 36.html Healthy Hint: To keep your nervous system

healthy, eat foods containing anti-oxidants, vitamins, and minerals, to keep your nervous systems control center (the brain) healthy. us-system.jpg The Digestive System ms/Digestive_AH4/Digestive%20system.gif The Digestive System My 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 systems 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. Internet Paragraph 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 Healthy Hint: Eat fiber forintestine a healthy system,

The trillions of cells that make up your bodys 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. Internet The 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. l http://www.williamsclas Work/ImagesCellBrick s/OrganSystem.jpg The Respiratory System The Respiratory System My Paragraph Your 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 dont stop breathing. Internet Paragraph The cells in your body need oxygen. You wouldnt 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. The Heart http:// wp-content/uploads/ 2009/03/heart-blending.jpg The Heart My Paragraph 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 bodys 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. 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.
