Thick wall

Vedclass · Answer

(A) The pulmonary artery is an artery,and like all arteries,it possesses a thicker wall compared to veins to withstand higher blood pressure. Veins are characterized by having thinner walls and the presence of valves to prevent the backflow of blood. Since the pulmonary artery is an artery,it does not have valves,whereas veins do. Therefore,the pulmonary artery differs from a vein by having a thicker wall and lacking valves. However,looking at the options provided,the question asks how the pulmonary artery differs from a vein. Since the pulmonary artery has a thick wall (unlike the thin wall of a vein) and lacks valves (unlike the presence of valves in a vein),option $(A)$ is the most accurate description of the structural difference.
