Human: What is the difference between a stoma and an ileostomy? Assistant: 
A stoma is a surgically created opening that allows waste to pass from the body into a bag or pouch. An ileostomy is a type of stoma where the end of the small intestine is brought through the abdominal wall and connected to the outside of the body. The purpose of an ileostomy is to allow for the drainage of stool from the lower part of the digestive system.
