Everybody has a skeleton. It is made
up of a lot of bones. The skeleton
gives your body the structure it has,
lets you move in several ways, and
protects your internal organs.

The skeletal system has 206 bones. When you are little you
have 350 bones but as you grow some of your bones join together to make
one bone. There are four general categories of bones. Long bones, flat
bones, short bones, and irregular bones. The skeletal system has three
major jobs. It protects our vital organs such as the brain, the heart, and the
lungs. It gives us the shape we have and it allows ourselves to move.
Healthy Hints
Exercise Regularly
Eat Dairy Foods for Calcium
Play Carefully
Sit Up Straight
There are more than 600 muscles in our
body. The muscular system consist of three different types of
muscle tissues : skeletal, cardiac, and smooth. Muscles help
you move. The muscles are attached to the skeleton, which
provides the pulling power for us to move around. The
different types of muscle tissues have the ability to contract,
which then allows body movements and functions. The main
job of the muscular system is to provide movement for the
body. Muscles help in pumping blood all over your body, to
carrying your heavy backpack.
Muscles are divided into two other groups
according to their functions, the involuntary muscles, and the
voluntary muscles. The muscles which we can control are
called voluntary muscles. The ones we can not control are
involuntary. The heart, is an example of involuntary muscle.
Your hands are examples of voluntary muscles.

You would be surprised to know that it is the skin,
which anyone might not think as an organ. No matter what you
think of it, your skin is very important. Your skin covers and
protects everything inside your body. Without skin, your muscles,
bones, and organs would be hanging out all over the place. Skin
holds everything together.
http://kidshealth.org/kid/htbw/htbw_main_page.html
The skin is the largest organ of the body. It
weighs about 8 pounds. It covers 22 square feet. Our
skin is composed of a complex system of cell layers,
nerves, and glands. It protects us and connects us to the
outside world.
Healthy Hints
Avoid Sunburns
Put On Sunscreen

The brain controls everything. It sends messages to the
rest of your body. From moving your hand, to pumping blood from your heart to
the rest of your body. It’s like the boss of your body. It controls everything even
when you’re asleep. Not bad for something that looks like a big, wrinkly, gray
sponge. Your brain has several different parts that work together. These five
parts are the cerebrum, the cerebellum, the brain stem, the pituitary gland, and
the hypothalamus.

The nervous system is a very complex system in the
body. It is divided into two main parts. The central nervous system (CNS) and
he peripheral nervous system. The spinal cord and the brain make up the CNS.
The main job of the CNS is to get the information from the body and send out
nstructions. The peripheral nervous system is made up of all of the nerves and
he wiring. This system sends the messages from the brain to the rest of the
body.

Even before you eat, when you smell a tasty food,
see it, or think about it, digestion begins. Saliva begins to form in
your mouth. When you do eat, the saliva breaks down the
chemicals in the food a bit, which helps make the food mushy and
easy to swallow. Your tongue helps out, pushing the food around
while you chew with your teeth. When you're ready to swallow, the
tongue pushes a little bit of mashed-up food called bolus toward
the opening of your esophagus, the second part of the digestive
tract.
http://kidshealth.org/PageManager.jsp?lic=1&article_set=54048&cat_id=20607
The digestive system includes the mouth, the
esophagus, the liver, the pancreas, the stomach, the
large intestine, the small intestine, the gall bladder, and
the rectum. The digestive system breaks down and
handles food.

DON’T Over Eat

The system is made up of the vessels and muscles that help and
control the flow of the blood circle the body. This process is called
circulation. The main parts of this system are the heart, arteries, capillaries
and veins.
Healthy Hints
 Get aerobic exercise

As blood begins to circulate, it leaves the heart from the left
ventricle and goes into the aorta. The blood leaving the aorta is full of
oxygen. Oxygen is important for the cells in the brain and the body to
do their work. The oxygen rich blood travels throughout the body. On
its way back to the heart, the blood travels through a system of veins.
As it reaches the lungs, the carbon dioxide is removed from the blood
and replace with fresh oxygen that we have inhaled through the lungs.
Blood!
Humans need oxygen to live. You get oxygen from
the air. Without oxygen we cannot survive for more than a couple
minutes. Breathing occurs automatically, you do not have to think about
it. You breathe in order to take oxygen into our bodies and get rid of
carbon dioxide. Oxygen is carried in the blood to the body's cells. The air
you breath out has hundred times more carbon dioxide than the air we
breath in.
http://library.thinkquest.org/5777/resp1.htm
The respiratory system is made up of the trachea, the lungs,
and the diaphragm. First, from the trachea you breathe in oxygen. Then,
when you breathe in your lungs take the oxygen in and the oxygen goes in
your blood to the rest of your body. Then when you breathe out your lungs
release carbon dioxide into the air. Your diaphragm (a muscle) helps the
lungs release the carbon dioxide by pushing against. It is located right
beneath your lungs. It also separates your chest and your belly.
Healthy Hints
Don’t Smoke
Breathe In Breathe Out!
Your heart is a muscle. It's located a bit to the left of the
middle of your chest. It's about the size of your fist. There are many
muscles in your body. In your arms, in your legs, in your back, and in
your behind.
http://kidshealth.org/kid/htbw/heart.html
There are four chambers in your heart. The
right atrium, the left atrium, the left ventricle, and the right
ventricle. Atria on both sides of the heart receive the
incoming blood first. Then, the blood is sent down to the
ventricles to be pumped out. The right side of the heart
receives “oxygen-poor” blood. The left side of the heart
receives “oxygen-rich” blood. The sound that comes from
your heart is the sound of the valves opening and
closing.
