Describe the different types of blood vessels by completing the following chart: (3 points total; 1/4 point per box) Blood vessel H... istological description/special characteristics Large arteries Medium arteries Arterioles Capillaries Medium veins Thick and full of elastic fibers enabling the walls to stretch due to increase blood pressure well-defined internal but thin external elastic laminae made up of 3-40 concentrically arranged layers of smooth muscle cells thin, with a fenestrated (porous) internal elastic lamina that diminishes as the arteriole tapers towards its terminal end and continues as a capillary, concentrically arranged layers of smooth muscle cells approximately 0.2 micrometers (0.02 mm) thick and is composed of a single layer of endothelial cells adhered to a basement membrane. not able to withstand high pressure somewhat on contraction of surrounding skeletal muscle and the pumping action of the heart to boost blood return move blood from the heart during ventricular diastole. elastic fibers store mechanical energy, which is converted into kinetic energy as the elastic fibers recoil and force the blood away from the heart. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .. . . . . .. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . .. . .. .. . . . . . . . . . . . . . . . . . .. . . . .
