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. It prevents a reflux of the bacteria-rich content from the large intestine into the small intestine.
