One well-known form of an artificial stoma is a colostomy, which is a surgically created opening in the large intestine that allows the removal of feces out of the body, bypassing the rectum, to drain into a pouch or other collection device. The historical practice of trepanation was also a type of stoma.he point of exiting is what is known as the stoma. For greatest success and to minimize negative effects, it is preferable to perform this procedure as low down in the tract as possible, as this allows the maximal amount of natural digestion to occur before eliminating fecal matter from the body.
An atheroma is an accumulation of degenerative material in the tunica intima (inner layer) of artery walls. The material consists of (mostly) macrophage cells, or debris, containing lipids (cholesterol and fatty acids), calcium and a variable amount of fibrous connective tissue.eins do not develop atheromata, unless surgically moved to function as an artery, as in bypass surgery. The accumulation (swelling) is always in the tunica intima, between the endothelium lining and the smooth muscle tunica media (middle layer) of the artery wall.
