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 blood that has just been oxygenated. From the left atrium, blood moves through the mitral valve into the left ventricle, which then pumps it to the rest of the body via the aorta. The right atrium handles deoxygenated blood coming from the body, the left ventricle is the main pump for systemic circulation, and the pectinate muscle is a muscular ridge within the atrial walls, not a chamber that receives blood. So the left atrium is the chamber that receives oxygenated blood from the lungs.
