The Circulatory System moves nutrients to the cells of the body to feed them and help them fight disease. The main parts of this system are the heart, blood and blood vessels. Arteries carry blood and the oxygen in it from the lungs to all of the other cells of the body. Once the oxygen is used, veins carry the blood back to the heart. Inside the heart are four chambers. Each chamber is a little pump that pushes the blood through the body. It takes 1-2 minutes for blood to circulate all around your body.
