Heart

Your fist is about the size of your heart. Your heart pumps about 2,000 gallons of blood through your body each day! Have you ever heard of a pump that can repair itself and run continuously for 80 years? People could never design something this amazing.

The heart has four chambers that work in pairs. Blood from your body flows into the right side of the heart and then to your lungs, where it picks up oxygen and gets rid of the waste gases. The blood then flows back to the heart, where the left side pumps the oxygen-rich blood to the rest of your body. Special valves in your heart allow the blood to flow in only one direction. Your heartbeat is actually the sound of these valves closing after the heart muscle relaxes.

Our creator God wants us to love him with all of our heart (Mark 12:30)!
