The lumen colored in red is lined by the intima (1 and 2)A single layer of squamous epithelium called the endothelium (1), is supported by the connective tissue and the internal elastic membrane of the basal lamina (2).The tunica media is made of smooth muscle(3) and the external elastic membrane (4).Variable amounts of elastin proteoglycans, and reticular fibres are intermixed within the media. The tunica adventitia (5) is the outer layer and consists of longitudinally oriented collagenous fibres with some elastin and the vasa vasorum and lymphocytes.Ashley Davidoff MD Copyright 201833785c
