Question

Why do arteries have a thick or elastic wall?

Answer 1

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

Answer 2

Answer:

Blood pressure is high in the arteries as the heart pumps out blood into the arteries.

Hence, to withstand the high blood pressure and manage fast flow of blood, arteries have thick and elastic walls.
