Tunica adventita is composed mainly of
elastic and collagen fibers that give
support and protection
Tunica media is the middle and thickest
layer composed of elastic fibers and
smooth muscle fibers, helps with
regulation of diameter
Tunica intima is composed of squamous
epithelium, a basement membrane, and
elastic tissue
