[[Bile]], which is synthesized in the liver, is carried to the right and left hepatic ducts, which converge along with the Cystic duct to form the [[common hepatic duct]]. There it enters the superior end of the common bile duct and either empties into the second (and [[retroperitoneal]]) part of the duodenum, or enters the cystic duct to be stored in the gallbladder.
The inferior end of the common bile duct merges with the large [[pancreatic duct]] (duct of Wirsung) from the [[pancreas]], into the [[ampulla of Vater]]. There, the two ducts are surrounded by the muscular hepatopancreatic sphincter ([[sphincter of Oddi]]) which if contracted, prevents [[bile]] from entering the small intestine.
