Anatomy - Anastomosis technique, biliodigestive, according to Hepp-Couinaud

The bile duct transports bile from the liver to the duodenum. In this way, bile contributes to the digestion of fatty foods. The bile ducts begin intrahepatically with the right and left hepatic ducts (ductus hepaticus dexter et sinister), which descend from the liver. When these two ducts meet, they form the common hepatic duct. As this duct continues to the duodenum, it is joined by the cystic duct, which comes from the gallbladder (Vesica biliaris). Together, they form the common bile duct, which opens into the duodenum. The major duodenal papilla (Vater's papilla) acts as a sphincter that regulates the flow of bile from the common bile duct into the duodenum.
