chambers of the heart
the heart has four chambers: two atria and two ventricles.
- the right atrium receives oxygen-poor blood from the body and pumps it to the right ventricle.
- the right ventricle pumps the oxygen-poor blood to the lungs.
- the left atrium receives oxygen-rich blood from the lungs and pumps it to the left ventricle.
- the left ventricle pumps the oxygen-rich blood to the body.
