Arteries and veins have thick walls to resist the forceful expulsion of blood from the heart during circulation of blood.

The ventricles of the heart have thicker muscular walls than the atria. This is because blood is pumped out of the heart at greater pressure from these chambers compared to the atria. The left ventricle also has a thicker muscular wall than the right ventricle.
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 nees for the strength and elasticity of the arteries, so the walls of the veins are thin and almost floppy.
