Small vein
Venules continue into small veins, which possess a thin tunica media, composed of scattered smooth muscle, and a prominent tunica adventitia. Like venules, veins also possess valves. The wall of the small vein is much thinner and less regular than that of the small artery it accompanies. 100x
