Venule

A venule is compared with its accompanying arteriole. Larger venules, as seen here, have a thin tunica media of scattered smooth muscle cells and a tunica adventitia. The arrangement of the cells in the wall of the venule is not as uniform as is that of the arteriole, which demonstrates a thicker wall with distinct layers of smooth muscle cells. 400x
