Tutorials and quizzes on the circulation of blood and the anatomy structure and physiology of blood vessels using interactive animations and diagrams. Since the pressure within arteries is relatively high the vasa vasorum must function in the outer layers of the vessel or the pressure exerted by the blood passing through the vessel would collapse it preventing any exchange from occurring.
