"The circulatory system is made up of the vessels and the muscles that help and control the flow of the blood around the body. This process is called circulation. The main parts of the system are the heart, arteries, capillaries and veins. As blood begins to circulate, it leaves the heart from the left ventricle and goes into the aorta. The aorta is the largest artery in the body. The blood leaving the aorta is full of oxygen. This is omportant for the cells in the brain and the body to do their work. The oxygen rich blood travels throughout the body in its system of arteries into the smallest arterioles. On its way back tot he heart, the blood travels through a system of veins. As it reaches the lungs, the carbon dioxide (A waste product) is removed from the blood and replaced with fresh oxygen that we have inhaled through the lungs."
 * Basically, this segment is explaining how the circulatory system works. The blood flows through the body giving oxygen to the places it's needed. The circulatory system is important during exercise because without oxygen, our body would shut down.

"The circulatory system is responsible for transporting materials throughout the entire body. It transports nutrients, water, and oxygen to your billions of body cells and carries away wastes such as carbon dioxide that body cells produce. It is an amazing highway that travels through your entire body connecting all your body cells. Parts of the Circulatory system: 1. The Heart 2. The Blood 3. The Blood Vessels

The Heart: The heart is an amazing organ. The heart beats about 3 BILION times during an average lifetime. It is a muscle about the size of your fist. The heart is located in the center of your chest slightly to the left. It's job is to pump your blood and keep the blood moving throughout your body

It is your job to keep your heart healthy and there are three main things you need to remember in order to keep your heart healthy: 1. Exercise on a regular basis. Get outside and play. Keep that body moving (walk, jog, run, bike, skate, jump, swim). 2. Eat healthy. Remember the fod pyramid and make sure your eating your food from the bottom to top. 3. Don't smoke!

The Blood: The blood is an amazing substance that is constantly flowing through our bodies. This website explains EVERYTHING about the circulatory system, what it does, how to keep your heart healthy, and what's in your blood that makes it such a key component to humans.
 * Your blood is pumped by your heart
 * Your blood travels through thousands of miles of blood vessels right within your own body
 * Your blood carries nutrients, water, oxygen and waste products to an from your body cells
 * A young person has about a gallon of blood. An adult has about 5 quarts
 * Your blood is not just a red liquid but rather is made up of liquids, solids and small amounts of oxygen and carbon dioxide"
