Which vessels carry oxygenated blood from the lungs to the right atrium?

Explanation:
Oxygenated blood from the lungs returns to the heart through the pulmonary veins and enters the left atrium. The right atrium, by contrast, receives deoxygenated blood from the body via the superior and inferior vena cavae. The pulmonary arteries carry blood to the lungs and are deoxygenated, not oxygenated, while the vena cavae bring blood to the right atrium. So, while the vessels from the lungs are indeed pulmonary veins, they deliver to the left atrium, not the right.
