What chambers of the heart receive blood

The left and right atrium

Explanation:

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.
