Structure/Morphology

The left hepatic duct is formed by the merging of lateral and medial branches and carries bile from the left liver.

Left segmental ducts that receive bile from segments II and III unite to form the lateral branch of the left hepatic duct.

Key Features/Anatomical Relations

Once the hepatic branches merge, the left hepatic duct becomes extrahepatic and runs along the inferior edge of liver segment IV for several centimeters. It is longer and more horizontally oriented than the right hepatic duct. It ends in the porta hepatis where it merges with the right hepatic duct to form the common hepatic duct (Standring, 2016).

Function

The branch of the left hepatic duct transmits bile from segments II and III of the left liver to the left hepatic duct and on to the common hepatic duct.
