The ilium is about 3 meters long, and contains villi similar to the jejunum. It absorbs mainly vitamin B12 and bile acids, as well as any other remaining nutrients. It joins to the cecum of the large intestine at the ileocecal junction.

A sphincter connects the two, preventing back flow. Below the junction is the appendix, which is essentially the tapering off of the large intestine into a rat tail like shape. Matter is supposed to continue up through this part of L.I. hence it's named the ascending colon.
What three parts make up the small intestine?
The small intestine is about 6-7 meters long. The first portion is called the duodenum and is about 20-25 cm long. There are 4 parts to the duodenum: (1) superior portion, (2) descending poriton, (3) inferior protion, (4) ascending poriton. The second protion is called the Jejunum and the proximal 2/5 of the small intestine (excluding the duodenum). The last portion is called the Ileum and composes the distal 3/5 of the small intestine.
