Caption: Anatomy of the extrahepatic bile ducts. Extrahepatic bile ducts are small tubes that carry bile outside of the liver. They are made up of the common hepatic duct (hilum region) and the common bile duct (distal region). Bile is made in the liver and flows through the common hepatic duct and the cystic duct to the gallbladder, where it is stored. Bile is released from the gallbladder when food is being digested.2007-01-16 Date last modified: 2015-06-12
