Answer : 3. "Veins have valves; arteries do not."
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.
