The left and right atrium
Explanation:
The heart has four chambers: two atria and two ventricles.

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.
