What term describes the network that supplies the heart muscle with oxygenated blood?

• A. Coronary Arteries
• B. Systemic Arteries
• C. Pulmonary Arteries
• D. Coronary Veins

Answer: (A)

The heart’s own blood supply to its muscle comes through the coronary arteries. These arteries branch from the aorta just above the aortic valve and wrap around the heart to deliver oxygen and nutrients to the myocardium, supporting continuous contraction. Systemic arteries carry oxygenated blood to the rest of the body, not specifically to the heart. Pulmonary arteries carry deoxygenated blood from the right ventricle to the lungs. Coronary veins drain blood from the heart muscle back toward the right atrium. So the vessels that provide the heart muscle with oxygenated blood are the coronary arteries.
