Which of the Following Supplies Oxygenated Blood to the Heart

Question

Which of the following supplies oxygenated blood to the heart muscle?
A) Coronary arteries
B) Pulmonary artery
C) Pulmonary veins
D) Cardiac veins

Accepted Answer

Coronary arteries supply oxygenated blood to the heart muscle, while the pulmonary artery carries deoxygenated blood away from the heart to the lungs. Pulmonary veins carry oxygenated blood from the lungs back to the heart, but they do not supply the heart muscle itself. Cardiac veins drain deoxygenated blood from the heart muscle and return it to the right atrium, but they do not supply oxygenated blood to the heart muscle.
