Why Are Arteries Thick Walled And Veins Thin Walled. Veins have thin walls as compared to arteries because the arteries carry blood from heart with high pressure and therefore to withstand the pressure it has thick walls whereas veins carry blood from different parts of the body and has less. All arteries have relatively thick veins have no need for thick walls as they tend to not have to withstand high pressures like arteries.
(a) arteries and (b) veins share the same general features, but the walls of arteries are much thicker because of the higher pressure of the.
Structure and function of arteries, capillaries and veins. Their thickness is medium.on the other hand capillaries have very thin permeable walls because a lot of materials are transferred at. Arteries are round and thick walled and veins are irregularly shaped and thin walled. Due to the tendency for higher and fluctuating pressures in arteries, artery walls are thicker than venous walls.
