Bile is produced by the liver and stored in the gallbladder. It aids in digestion by emulsifying fats in the small intestine. Bile is secreted from the liver into bile canaliculi and stored in the gallbladder. Upon eating, bile is discharged from the gallbladder through the bile duct into the duodenum where it helps to digest lipids. Bile salts are reabsorbed in the ileum through enterohepatic circulation and returned to the liver to be reused.
