Right Hepatic Duct

Ductus hepaticus dexter

The right hepatic duct is formed by the merging of segmental intrahepatic ducts and carries bile from the right liver.

Structurally, the right hepatic duct has a mucosal layer and a fibrous layer (Standring, 2016). The mucosal layer consists of a single cell epithelium on the luminal surface, small longitudinal folds, mucous glands, and loose connective tissue.

The fibrous layer deep to this isn’t well formed in the right hepatic duct and consists of mostly connective tissue and elastin, with few smooth muscle fibers (Gulwani, 2012).

Key Features/Anatomical Relations

The right hepatic duct becomes extrahepatic and runs vertically just 1–2 cm on the right side of the porta hepatis. It ends in the porta hepatis where it merges with the left hepatic duct to form the common hepatic duct (Standring, 2016).


The right hepatic duct transmits bile from the right liver to the common hepatic duct.

Although the confluence of the hepatic ducts is situated outside of the parenchyma of the liver, for convenience an intrahepatic bile duct is defined as any bile duct proximal to the confluence of the right and left hepatic ducts.
