Quizplus · Accepted Answer

The oxygenated blood is transported to the heart through the pulmonary veins, which bring blood from the lungs to the left atrium of the heart. The pulmonary arteries carry deoxygenated blood from the heart to the lungs. The bronchial arteries and veins supply and drain blood to and from the tissues of the bronchi and lungs, but they do not transport oxygenated blood to the heart.
