Capillary wall structure
WebThe capillaries connect the two types of blood vessel and molecules are exchanged between the blood and the cells across their walls. Arteries carry blood away from the heart Arteries WebThe wall of an artery consists of three layers. The innermost layer, the tunica intima (also called tunica interna), is simple squamous epithelium surrounded by a connective tissue basement membrane with elastic fibers. The middle layer, the tunica media, is primarily smooth muscle and is usually the thickest layer.
