Bile, which is synthesized in the liver, is carried via the right and left hepatic ducts, both being converged to form the common hepatic duct, the cystic duct opens the lower end of common hepatic duct forming common bile duct.that is the cystic duct enters the superior end of the common bile duct and the bile either empties into the second (retroperitoneal]]) part of the duodenum at times of digestion, or enters the cystic duct to be stored in the gallbladder in the resting time as spincter oddi is contracted .The bile finds its route to gallblader via cystic duct to be stored there at gall blader bag.and also concentration of bile takeplace at gallblader.The bile is to be realeased from storage bag to duodenum by secretion of cholycystokinin a local hormone from duodenal mucosa by a stumuli of passage of fatty meal in duodenum.
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.
