Detailed explanation-1: -But unlike the arteries, the venous pressure is low. Veins are thin-walled and are less elastic. This feature permits the veins to hold a very high percentage of the blood in circulation.
Detailed explanation-2: -The walls of large arteries, especially the aorta, lose elasticity over time, and this process results in increased arterial stiffness. Arterial stiffening, at least in part, reflects gradual fragmentation and loss of elastin fibers and accumulation of stiffer collagen fibers in the arterial wall [1].
Detailed explanation-3: -Arteries have thick, elastic and muscular walls. Arteries are the first vessels that the heart pumps blood through, they experience the highest blood pressure, so they have thick elastic walls to withstand the high pressures. Veins have thin and non-elastic walls.
