The anterior border of the liver is lifted upwards (brown arrow). Gallbladder with Longitudinal section, pancreas and duodenum with frontal one. Intrahepatic ducts and stomach in transparency.

Intrahepatic bile ducts compose the outflow system of exocrine bile product from the liver.

They can be divided into:^[1]

Lobar ducts (right and left hepatic ducts) - stratified columnar epithelium.
Interlobar ducts (between the main hepatic ducts and the interlobular ducts) - pseudostratified columnar epithelium.
Interlobular bile ducts (between the interlobar ducts and the lobules) - simple columnar epithelium.
Intralobular bile ducts (cholangioles or Canals of Hering) - simple cuboidal epithelium, then by hepatocytes
Bile canaliculi - two half-canaliculi formed by the hepatocytes facing the perisinusoidal space
