The ileum (/ ˈ ɪ l i əm /) is the final section of the small intestine in most higher vertebrates, including mammals, reptiles, and birds. In fish , the divisions of the small intestine are not as clear and the terms posterior intestine or distal intestine may be used instead of ileum. [ 2 ]
The small intestine supports the body's immune system. [20] The presence of gut flora appears to contribute positively to the host's immune system.

The end of the ileum is then brought out through an opening (a stoma) in the abdominal wall. The residual small bowel is reanastamosed with the residual terminal ileum, usually seated inferior relative to the anastomosis. [2] [3] The urine is collected through a bag that attaches on the outside of the body over the stoma.
Ileal conduit urinary diversion, also known as "Bricker's loop": The two ureters that transport urine from the kidneys are detached from the bladder, and then attached so that they will empty through a piece of the ileum. One end of the ileum piece is sealed off and the other end is brought to the surface of the abdomen to form the stoma.
