Ileum, the final and longest segment of the small intestine. It is specifically responsible for the absorption of vitamin B12 and the reabsorption of conjugated bile salts.
Macroscopic anatomy. The ileum is the last of the three parts of the small intestine. The transition from the jejunum to the ileum is not sharply marked. At the distal end the ileum opens into the large intestine. At the junction between the ileum and the caecum lies the ileocecal valve (ileal ostium), a functional sphincter formed by the circular muscle layers of both the ileum and cecum.
