The Structure of Blood Vessels

Tunica Interna (also called the Tunica Intima)

– smooth inner layer that repels blood cells and platelets – endothelium of simple squamous cells on a basement membrane

Tunica Media

– middle layer of smooth muscle, collagen, elastic fibers – smooth muscle causes vasoconstriction and vasodilation

Tunica Externa (also called the Tunica Adventitia)

– outermost layer of loose connective tissue – holds vessels in place

lymphocytes

SLIDE 26

Lymphatic vessel (L) next to a small vein (V). Lymphatics due not contain

RBCs, but often contain a few lymphocytes. Taken from Wheater’s Functional Histology, a text and colour atlas, p. 156, Figures 8.22 and 8.23.
