Last section of the small intestine absorbing vitamin B12 and completing absorption.
Third and last part of the small intestine, approximately 3.5 meters long, specialized in the absorption of vitamin B12, bile acids, and water.
The ileum completes the absorption process started in the duodenum and jejunum. It specifically absorbs vitamin B12 (cobalamin), bile acids, and remaining nutrients. The ileum also absorbs a significant amount of water, which is crucial for maintaining the body's fluid balance. The ileum mucosa contains lymphoid tissue that plays an immune role. At the end of the ileum is the ileocecal valve that controls the passage of undigested residues to the colon.
