Venule

The characteristics of a venule can be identified in this electron micrograph: a wide lumen surrounded by a layer of endothelial cells and no additional tunics. While capillaries and small venules have a similar appearance, the wall of the venule is composed of multiple endothelial cells and possesses a wider lumen. 2500x
