Origin

The segmental III vein originates from the umbilical part of the left branch of the hepatic portal vein.

Course

After branching from the umbilical part of the left branch of the hepatic portal vein, the segmental III vein travels anteriorly and slightly inferior to enter segment III of the liver (Standring, 2016).. This vein continues to branch into smaller venous branches, which ultimately terminate as portal venules. These portal venules drain into the hepatic sinusoids.

Branches

There are no named branches.

Supplied Structures

The segmental III vein supplies nutrient-rich venous blood from the digestive tract to segment III of the left liver.
