Heart Function Worksheet
A pump that never rests
The heart is a strong muscle that pumps blood around the body. It has four chambers. Blood returning from the body travels to the right side of the heart and is sent to the lungs. In the lungs, blood takes in oxygen. It then returns to the left side of the heart, which pumps it around the body. Blood carries oxygen to cells, where it is needed. The heart keeps working while you sleep, too. A resting heart rate varies from person to person and can change with activity, so there is no single beat count that is right for everyone.
