Hepatic ducts carry bile from the liver, through a series of other ducts, eventually to the duodenum. They consist of right hepatic duct, left hepatic duct and common hepatic duct.
Right and left hepatic ducts:
The smallest interlobular tributaries of the bile ducts are situated in the portal canals of the liver. These tributaries receive the bile canaliculi and join one another to form progressively larger ducts. Eventually, at the porta hepatis, they form the right and left hepatic ducts. The right hepatic duct drains the right duct of the liver, while the left drains into left lobe, caudate lobe and quadrate lobe.
After emerging from the porta hepatis and taking a short course, the hepatic ducts unite to form the common hepatic duct.
Common hepatic duct:
Common hepatic duct is about 1.5 inches long. It descends within the free margin of the lesser omentum. It is joined on the right side by the cystic duct from the gall-bladder to form the bile duct.
