The aorta is the largest ______ of the body.

The aorta is the largest ______ of the body.

• A. Vein
• B. Capillary
• C. Artery
• D. Atrium

Answer: (C)

The aorta is the largest artery in the body. This makes sense because arteries are vessels that carry blood away from the heart, and the aorta is the main conduit for oxygenated blood leaving the left ventricle to supply the whole body. Its walls are thick and elastic to withstand the high pressure of the heart’s output. Veins return blood to the heart and have thinner walls, capillaries are tiny vessels where exchange occurs, and an atrium is a chamber of the heart, not a vessel.
