How do thick artery walls and valves in veins suit their functions?

Answer and explanation

Correct answer: Arteries withstand high blood pressure, while valves in veins help prevent backflow at lower pressure.

Arteries carry blood away from the heart under relatively high pressure, so their walls are thick and elastic. Blood flows through veins at lower pressure, and their valves help prevent it from flowing backwards.
