Question

why artries have thicker and elystic walld as compaired to vein ​

Answer 1

Answer:

Arteries and arterioles have thicker walls than veins and venules because they are closer to the heart and receive blood that is surging at a far greater pressure (Figure 2). ... This is critical because blood flow becomes sluggish in the extremities, as a result of the lower pressure and the effects of gravity.
