Colostomy → It is formed from "colo-" (from Latin "colon", meaning the large intestine) and "-stomy" (from Greek "stoma", meaning mouth or opening). The word refers to the creation of an opening in the abdominal wall for the colon, allowing waste to exit the body.
Think of 'colon' as the part of the intestine and 'stoma' as an opening — a colostomy is an opening created for the colon.
