The intima of elastic artery is thicker than the muscular artery

Media: - the irregular line is elastic tissueThe nucleus for smooth muscle (not fibroblast or fibrocyte) with ill-definedcytoplasm

the smooth muscle is important to produce collagen and elastic, not tomake contraction!!!

The vasa vasorum is more in elastic artery than muscular artery and morein the large vein because most of the blood inside it is poorly oxygenated

What is the most predominant tissue here? and why?Elastic tissue, to convert the intermittent blood flow to continues byexpansion and recoiling.Collagen and smooth muscle for strength

The adventitia contains mostly collagen and little elastic

In the artery the media is thicker than the adventitia while it is the oppositein vein

The vein wall contains mainly collagen

What is the main function of venules? Diapedese

Arteriole gives met-arteriole which gives capillary then gives venuleBetween the meta-arteriole and the capillary there is precapillary sphincterThe sphincter and the met-arteriole poorly innervated by sympathetic butexpand and narrow by local metabolite.
