Which vessels return blood from the lungs to the heart?

Explanation:
In pulmonary circulation, blood returns to the heart from the lungs through the pulmonary veins. After gas exchange in the lungs, oxygen-rich blood travels via these veins into the left atrium, setting the stage for systemic circulation. The other vessels have different roles: pulmonary arteries carry blood from the heart to the lungs for oxygenation, the aorta distributes blood from the heart to the body, and the inferior vena cava returns deoxygenated blood from the lower body to the right atrium. So the vessels that bring blood back from the lungs to the heart are the pulmonary veins.
