Which vessel carries oxygen-rich blood from the lungs to the left atrium?

Explanation:
Oxygenated blood returns from the lungs to the heart through the pulmonary veins. These vessels connect the lungs to the left atrium, delivering blood that’s rich in oxygen. The left pulmonary veins specifically drain the left lung into the left atrium. By contrast, the pulmonary arteries carry blood to the lungs to be oxygenated (they carry deoxygenated blood), and the superior vena cava brings deoxygenated blood from the body into the right atrium.
