Arteries are characterised by
Athick elastic walls, blood under high pressure, no valves
Bthin walls with valves, blood under low pressure
Cthin walls, blood flows towards the heart
Dvalves throughout, carrying deoxygenated blood only
Answer & Solution
Correct answer: A. thick elastic walls, blood under high pressure, no valves
Arteries carry blood away from the heart under high pressure, so they have thick, elastic walls and no valves (valves are in veins, where pressure is low).
