TODO - note terminological problems. WP says tunica external layer of blood vessel. FMA says tunica externa = adventitia, and is FMA adventitia covers other kinds of vessels. Here we opt for a lengthier name that attempts to disambiguate. There is no precise FMA equivalent, as FMA has tunica externa of arteries, veins, genital ducts etc as siblings
The outermost layer of a blood vessel, surrounding the tunica media. It is mainly composed of collagen. The collagen serves to anchor the blood vessel to nearby organs, giving it stability[Wikipedia:Tunica_externa_(vessels)].
