Venule

A venule and accompanying arteriole show the variation between their walls.  The venule has a tunica intima and a thin tunica adventitia of connective tissue.  The arteriole has a tunica intima, a single layer of smooth muscle forming tunica media, and a thin tunica adventitia.  The lumen of the arteriole was artifactually expanded during fixation by vascular perfusion.  1000x
