What is a stoma, and how is it formed?
assistant
A stoma is a surgically created opening in the body that allows for the elimination of bodily waste. It is usually made from the skin or tissue of the abdomen, but can also be made from other parts of the body such as the nose, ear, or vagina. The stoma is usually connected to an appliance called an ostomy bag, which collects the waste and stores it until it can be disposed of by the user.
