Where the ileum is, in 3D
The ileum is the last part of the small intestine, joining the large intestine. It is part of the small intestine and belongs to the digestive system. It is the remaining three-fifths or so of the small intestine and lies mostly in the lower right abdomen. Its wall has many Peyer's patches of lymphoid tissue, and it joins the caecum at the ileocaecal valve.

What else can you see alongside the ileum?
The BAHI BODY 3D model of the small intestine also shows the duodenum and jejunum.
Where is the small intestine?
The small intestine is the long tube between the stomach and the large intestine, running through the duodenum, jejunum and ileum.
Where does the ileum join the large intestine?
In the lower right abdomen, at the ileocaecal valve, where it opens into the caecum, the first part of the large intestine.
