Quizplus · Accepted Answer

The four pulmonary veins, two from the right lung and two from the left lung, carry oxygenated blood from the lungs to the left side of the heart. All other veins carry deoxygenated blood. The superior vena cava returns deoxygenated blood from systemic circulation to the right atrium. The pulmonary arteries carry deoxygenated blood from the right side of the heart into the lungs.
