The morphology of healthy arteries


Healthy arteries consist of three tissue layers: First, the endothelium (intima), which forms a barrier between the subendothelial tissue and the blood. It is a continuous layer covering the complete surface of all arteries. As a selective barrier, it regulates the exchange of compounds between blood and underlying tissues. Second, the media consisting of contractile smooth muscle cells which mediate vasoconstriction and vasodilatation to maintain blood pressure. Third, the adventitia which is comprised of mostly fibroblasts. It embeds the artery in the surrounding tissue. The different tissues are separated by elastic laminas termed lamina elastica interna and externa.
