Which chamber receives oxygen-rich blood from the left lung?

• A. Right Atrium
• B. Left Ventricle
• C. Left Atrium
• D. Right Ventricle

Answer: (C)

Blood that has been oxygenated in the lungs returns to the heart through the pulmonary veins and ends up in the left atrium. This chamber serves as the receiving room for oxygen-rich blood from the lungs. From the left atrium, blood moves through the mitral valve into the left ventricle, which then pumps it to the rest of the body. The other chambers have different duties: the right atrium collects deoxygenated blood from the body, the right ventricle sends blood to the lungs, and the left ventricle pumps to the body. Specifically, the left lung feeds oxygenated blood into the left atrium via the pulmonary veins.
