=How Blood Travels Through the body... =

==**B****lood ****travels through the body in a figure eight pattern, and it all starts with the heart which is one of the most important organ you need to live. Blood travels to your pumping heart, though your lungs, then back to your heart. Then blood travels out of your heart, throughout your body then again back to your heart (see figure eight starts with the heart ends with the heart). This "Figure Eight" uses the help of 3 types of blood vessels; Arteries, Capillaries, and veins, these blood vessels contribute to blood flowing throughout your body. The Arteries help by carrying blood away from the heart to get the blood flowing in other ways, The Aorta is one of the largest Arteries in the body! Then from the Arteries your blood flows through tiny little vessels called Capillaries which substances are exchanged between blood and body cells. Lastly your blood will flow to your veins that carry blood back to your heart... which is the end of your "Figure Eight". **==


==**The Cardiovascular System is a very important system in your body because it consists of your heart, blood, and blood vessels. So the Cardiovascular system delivers substances that we need to cells and then carries waste products away from our perfectly good cells. Also your blood contains certain cells that can help you fight diseases. So if you really want a healthy body and pretty healthy blood pumping in your veins then that nay suggest that our Cardiovascular system is one of the most important systems you need. **==
