Heterogeneity of the intrahepatic biliary epithelium

Table 1 Terminology and relationship between human and rat intrahepatic bile ducts

Terminology for human bile ducts(diameter inμm)	Terminology for rat bile ducts(diameter inμm)
(Large bile ducts)
Hepatic ducts (> 800)
Segmental ducts (400-800)
Area ducts (300-400)
(Small bile ducts)
Septal bile ducts (100-300)
Interlobular bile ducts (15-100)	Large bile ducts (> 15)
Bile ductules (cholangioles) (< 15)	Small bile ducts (< 15)

These data have been obtained from studies[8,12,13] aimed to define the morphological characteristics of the biliary epithelium of rats, and humans. Reproduced with permission from Ref 2.
