Which chamber receives pulmonary venous blood returning from the lungs?

Explanation:
Pulmonary venous blood coming back from the lungs is oxygenated and returns to the heart into the left atrium. This chamber collects the oxygen-rich blood and passes it through the mitral valve into the left ventricle, which then pumps it to the body via the aorta. The right atrium, by contrast, receives deoxygenated blood from the body, and the right ventricle pumps blood to the lungs. So the left atrium is the chamber that receives pulmonary venous return.
