Adventitia - Definition


Adventitia is the external membrane of the canals, and the arteries in particular, that make up the human body. It is an anatomical term that describes the external arterial lining that is composed of collagen fibers, elastics, and connective tissue (the supporting tissue of the body). In the adventitia are the capillaries that supply the lining of arteries and the nerve fibers which allow for a certain control over the size of the canal and for the contraction or dilation of the vessels.
