Do veins have thick walls?
The thicker and more muscular walls of arteries help them to withstand and absorb the pressure waves which begin in the heart and are transmitted by the blood. They do not have the need for the strength and elasticity of the arteries, so the walls of the veins are thin and almost floppy.
