Which statement about arteries and veins is CORRECT?
A) For an artery and vein of the same diameter, the vein would have a thicker wall.
B) Veins contain valves and arteries do not.
C) Blood pressure is lower in arteries than in veins.
D) When empty, an artery is more likely to be collapsed (flattened) than a vein.
E) Both arteries and veins are under pressure.
Arteries
Blood vessels that carry oxygen-rich blood away from the heart to the body.
Veins
Blood vessels that carry blood towards the heart, often containing valves to prevent backflow.
Valves
Structures within the heart and veins that maintain one-way blood flow, preventing backflow and ensuring efficient circulation.

Final Answer :
B
Explanation :
Veins contain valves that prevent the backflow of blood, helping it return to the heart, especially from the lower parts of the body. Arteries, which carry blood away from the heart, do not have these valves because the blood is pushed through them by the heart's pumping action at a higher pressure.
