Concept:Arteries are strong vessels that carry blood away from the heart and do not have valves throughout their length.
Explanation:Arteries have thick, muscular, and elastic walls to withstand high blood pressure.
They carry blood away from the heart.
Most arteries transport oxygenated blood, except the pulmonary artery, which carries deoxygenated blood.
Valves are absent in arteries except for semi-lunar valves found near the heart.
Therefore, the feature "possess valves at intervals throughout their length" is not true for arteries.
Answer:A. possess valves at intervals throughout their length.
