Bile acids participate in lipid digestion and absorption in the small intestine and the majority are then reabsorbed in the ileum. These are extracted from the portal blood in the liver and re-secreted into bile, completing the '''entero-hepatic circulation''' of bile acids. | Bile acids participate in lipid digestion and absorption in the small intestine and the majority are then reabsorbed in the ileum.
