Structure of the Vascular System

The layers of the vascular system are all similar in veins and ateries. The difference of thickness of various layers constitute the functional differences in the two types of vessels.

Tunica Intima

A single-cell endothelial layer that provides friction free lining for blood flow.

Tunica Media
