- How often your heart pumps is called your pulse.
A Diagram of the Circulatory System
A Diagram of the Circulatory System
- The right atrium collects the deoxygenated blood from the body. It sends the blood to the right ventricle.
- The right ventricle pumps the deoxygenated blood to the lungs. Here the blood picks up oxygen and disposes of carbon dioxide.
- The lungs send oxygenated blood back to the left atrium which pumps it to the left ventricle.
- The left ventricle pumps the blood to the rest of the body.
