Quizplus · Accepted Answer

The pulmonary veins are the only vessels that carry oxygenated blood back to the heart. They empty into the left atrium of the heart. The inferior vena cava and superior vena cava bring deoxygenated blood from the lower and upper parts of the body respectively, while the pulmonary arteries carry deoxygenated blood from the heart to the lungs where it gets oxygenated. The ascending aorta carries oxygenated blood out of the left ventricle and into the systemic circulation.
