Quizplus · Accepted Answer

Oxygenated blood is transported from the lungs to the heart by the pulmonary vein. The pulmonary artery carries deoxygenated blood from the heart to the lungs for oxygenation. The superior and inferior vena cava transport deoxygenated blood from the body to the heart, and the coronary artery supplies blood to the heart muscle itself.
