The pulmonary veins are the only structures listed that transport oxygenated blood from the lungs to the heart. The pulmonary arteries carry deoxygenated blood from the heart to the lungs, the jugular veins drain deoxygenated blood from the head and neck, and the superior vena cava returns deoxygenated blood from the upper body to the heart.
