Lies outside the tunica interna. This layer contains muscle tissues (vascular smooth muscle) that are responsible for changing blood vessel diameter to adjust blood flow and pressure.
Tunica media
The outermost layer
Tunic externa
What does the tunic externa consist of?
Connective tissue (collagen fibers) to protect the vessels and anchor them to surrounding tissues
