why arteries walls are thin than the vein

It’s actually the opposite.
Arteries have thicker walls than veins to withstand the high pressure of the outflow of blood from the Heart.
:
The Circulatory System has, at the centre of it, the Heart. It pumps blood out at high pressure so that it can reach all the parts of the body quickly. To withstand the pressure of the blood coming out from the heart, arteries need thick walls.
The returning blood in the veins is under low(er) pressure. Because of the lower pressure, vein walls are thinner. However, veins also have one-way stop valves to keep blood from flowing backwards.
Hope my answer helps you!

Answer:
Why do veins have thin walls as compared to arteries?
Ans. Blood flow through vein does not exert pressure on the walls of veins. Due to this, they do not need thick walls. Hence, veins have thin walls as compared to arteries.
