Which vessel delivers oxygenated blood from the lungs to the left atrium?

Explanation:
Pulmonary veins. After gas exchange in the lungs, blood becomes oxygenated and returns to the heart through the pulmonary veins, which drain into the left atrium. This vessel set is unique in carrying oxygenated blood back to the heart, whereas the pulmonary arteries carry deoxygenated blood from the right side of the heart to the lungs. From the left atrium, the oxygen-rich blood goes to the left ventricle and then out to the body via the aorta.
