Why do veins have less collagen elastic fibers and smooth muscles than arteries?
Because blood in veins is under lower pressure than in arteries, so they do not need as many collagen fibres. In addition, as veins already have a wide diameter, they do not need to dilate that much hence they also dont contract that much (as opposed to artieries), so they have less elastic recoil, thus they have less elastic fibres. :)
Why don't capillaries have a thick elastic walls?
