The great vessels include which pair of vessels?

• A. aorta, superior vena cava
• B. pulmonary artery, inferior vena cava
• C. aorta, pulmonary veins
• D. coronary arteries, aorta

Answer: (A)

Great vessels are the large vessels directly connected to the heart, serving as the main pathways for blood to leave or return to it. The aorta is the primary artery carrying oxygenated blood away from the left ventricle to the systemic circulation, while the superior vena cava is the large vein that brings deoxygenated blood from the head, neck, and upper limbs back to the right atrium. These two vessels exemplify the major conduits tied to the heart, one as an outflow artery and the other as an inflow vein, which is why they’re commonly cited together when describing the great vessels. Other options include vessels not typically categorized with the classic great vessels in many teaching contexts (pulmonary veins deliver blood to the left atrium, which isn’t always listed among the great vessels; coronary arteries are smaller arteries that supply the heart muscle).
