Circulatory System

The circulatory system is a complex network of vessels and organs. It is like a pump (the heart) with tubes attached (arteries and veins). Its job is to pump blood from the heart to the cells and then back again to the heart. Blood takes oxygen and nutrients to the cells. The oxygen and nutrients pass into the body's cells, and then the waste products and carbon dioxide pass out of the cells into the blood to return to the heart.
