Question

Why do arteries need to be thick, muscular, and elastic?

to make our bodies strong for movement

to withstand the pressure of the blood that is being pumped by the heart

to pull the blood back to the heart from all areas of the body

to withstand changes in blood temperature

Answer 1

The answer is to withstand the pressure of the blood that is being pumped from the heart, because the pressure can change based on activity levels.

Answer 2

Arteries need to be thick, muscular and elastic IN ORDER TO WITHSTAND THE PRESSURE OF THE BLOOD THAT IS BEING PUMPED BY THE HEART.

The walls of the arteries are thicker and more muscular than that of veins because of the work that they perform. The arteries have thick and muscular walls, which help them to withstand and absorb the pressure waves that are generated as a result of blood pumping from the heart. The elasticity of the arteries help them to generate appropriate pressure for supporting blood flow.
