Question

Quizplus · Accepted Answer

Blood is returned to the right side of the heart by two large veins called the vena cavae. The superior vena cava returns blood from the upper half of the body, while the inferior vena cava returns blood from the lower half of the body. The aorta is a large artery that carries oxygenated blood away from the heart to the rest of the body. The pulmonary vein carries oxygenated blood from the lungs to the left side of the heart, not the right side. The pulmonary artery carries deoxygenated blood from the right side of the heart to the lungs, not blood that is returning to the heart.
