Which vessel returns oxygenated blood from the left lung to the left atrium?

Explanation:
Oxygenated blood from the lungs returns to the heart through the pulmonary veins, which lead into the left atrium. From the left lung, the left pulmonary vein carries the oxygen-rich blood into the left atrium, delivering it for systemic circulation. In contrast, the right pulmonary artery carries blood to the lungs (and is deoxygenated), the left coronary artery supplies the heart tissue itself, and the superior vena cava returns deoxygenated blood from the upper body to the right atrium. So the vessel that returns oxygenated blood from the left lung to the left atrium is the left pulmonary vein.
