Why is the heart a Double pump?
Blood carries oxygen and many other substances around your body. Oxygen from your blood reacts with sugar in your cells to make energy. The waste product of this process, carbon dioxide, is carried away from your cells in your blood.
Your heart is a single organ, but it acts as a double pump.
The first pump carries oxygen-poor blood to your lungs, where it unloads carbon dioxide and picks up oxygen. It then delivers oxygen-rich blood back to your heart. (Right side of your heart)
The second pump delivers oxygen-rich blood to every part of your body. (Left side of your heart)
Blood needing more oxygen is sent back to the heart to begin the cycle again. In one day your heart transports all your blood around your body about 1000 times.
