Which term describes a vessel that carries blood away from the heart?

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

Answer: (A)

Blood vessels that carry blood away from the heart are called arteries. This reflects their role in delivering the heart’s pumped blood into the systemic (and pulmonary) circuits. Arteries have thick, muscular, and elastic walls to withstand and regulate the high pressure of blood ejected with each heartbeat. In systemic circulation, they typically carry oxygen-rich blood; in the pulmonary circuit, the pulmonary artery carries blood away from the heart to the lungs and is part of your circulation even though it carries relatively deoxygenated blood. Other terms described here: veins return blood to the heart, capillaries are the tiny vessels where exchange with tissues occurs, and lumen is just the hollow interior of a vessel, not a vessel type itself.
