The front border of the liver has been lifted up (brown arrow).[1]
They can be divided into:[2]
- 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
