Which chamber receives oxygenated blood from the lungs?

Explanation:
Oxygenated blood from the lungs returns to the heart through the pulmonary veins and enters the left atrium. This chamber serves as the receiving room for lung-originating blood before it moves to the left ventricle via the mitral valve, after which the blood is pumped to the rest of the body. The right atrium, in contrast, collects deoxygenated blood from the body; the right ventricle sends blood to the lungs; and the left ventricle pumps oxygen-rich blood to the systemic circulation.
