Q:

Which of the following is true about veins?

A) Veins carry blood away from the heart, while arteries carry blood to the heart.	B) Veins are more muscular than arteries.
C) Veins have valves; arteries do not.	D) Veins have a smaller diameter lumen than arteries.

Answer & Explanation Answer: C) Veins have valves; arteries do not.

Explanation:

Veins are blood vessels that carry blood toward the heart. Most veins carry deoxygenated blood from the tissues back to the heart; exceptions are the pulmonary and umbilical veins, both of which carry oxygenated blood to the heart. In contrast to veins, arteries carry blood away from the heart.

Veins are less muscular than arteries and are often closer to the skin. There are valves in most veins to prevent backflow.
