What is the function of arteries?

• A. Transport blood away from the heart to the capillaries.
• B. Return blood to the heart.
• C. Exchange nutrients with tissues.
• D. Pump blood into ventricles.

Answer: (A)

Arteries carry blood away from the heart under high pressure, delivering it to tissues through smaller branches. Their thick, muscular walls help push blood forward and regulate flow as they branch into arterioles and eventually reach capillary beds for exchange. That’s why the function described—moving blood away from the heart to the capillaries—is correct. Veins return blood to the heart; capillaries are where nutrients and gases are exchanged with tissues; and the ventricles are the heart’s pumping chambers that push blood into the arteries, not the vessels that carry blood away.
