a. Arteries – thick walls, elastin, some smooth muscle. *Endothelium (inside lining) of arteries maintains hemostasis. Inhibits clotting of blood-keeps blood moving.

c. Capillaries – very thin, no elastin, no smooth muscle.
d. Venules – small amount of muscle & connective tissue.
e. Veins – larger veins have valves to prevent the back-flow of blood. |
