Abstract
The heart and the blood circulation are the transport system of the body. Blood carries substances and heat around the body. Blood is forced around the body through arteries, narrow capillaries and veins, by a muscular pump, the heart. Figure 19.1 shows that arteries always take blood from the heart to the capillaries of the lungs and to other parts of the body and that veins always take blood back to the heart. Blood flows from arteries to veins through capillaries.
