18.8.1. Blood Vessels—Structure and Clinical Needs

The cardiovascular system maintains homeostasis of the organism and mediates gas exchange, nutrient and waste transport, and immune defense. These critical functions are fulfilled by the extensive vasculature which consists of a network of blood vessels (arteries, veins, and capillaries). Blood vessels (except capillaries) are structurally built of three layers, which are named from the luminal side outward as the tunica intima (New Latin, “inner coat”), tunica media (“middle coat”), and tunica adventitia (“outer coat”) (Figure 18.17). The thickness of each layer varies greatly depending upon the size and type of vessel (arteries vs veins). Moreover, each structural ...
