Ductal drainage of the liver is via the bile duct system, which originates between the cells as bile canaliculi, joining to form bile ductule.
Segmental drainage to form the
common hepatic ducts, and finally
common bile duct
The ampulla represents the confluens of the bile and pancreatic ducts to drain into the duodenum.
Bile ducts accompany the hepatic artery and the portal vein throughout the liver. Bile, which is created in the hepatocytes, is secreted and collected after passing through the bile capillaries by the bile ducts, which join to form two large ducts that unite to form the hepatic duct. The bile is either carried to the gallbladder by the cystic duct or transported directly into the duodenum by the common bile duct.
anatomy of the bile duct the bile duct is anatomically characterized by its tubular nature its connections to the gallbladder and duodenum and pancreatic duct and its relationship to the portal vein and hepatic artery.
The liver cells are accompanied by bile canalliculi (small bile channels) which are situated between neighboring liver cells. These become confluent at the periphery of the liver lobule and form the bile ductule member of the portal triad.
This is an MRCP – magnetic resonance cholangiopancreatogram, showing a coronal view of the distal common bile duct becoming confluent with the pancreatic duct at the duodenum.
