Quizplus · Accepted Answer

The pulmonary vein is the vessel that carries oxygen-rich blood from the lungs back to the heart, where it is then pumped out to the rest of the body. The pulmonary artery, on the other hand, transports deoxygenated blood from the heart to the lungs where it is oxygenated. The vena cava carries deoxygenated blood from the body to the heart, while the coronary artery supplies oxygen and nutrients to the heart muscle itself.
