Origin
The umbilical part of the left branch of the hepatic portal vein is the segment of the left hepatic portal vein distal to the area that the ligamentum venosum (left umbilical vein) merges.
Course
The umbilical part of the left branch of the hepatic portal vein continues throughout the left portion of the liver.
Branches
The umbilical part of the left branch of the hepatic portal vein provides segmental branches to II, III, and IV of the liver. It may also give a branch to segment I of the liver. These branches continue to branch into smaller venous branches, which ultimately terminate as portal venules. These portal venules drain into the hepatic sinusoids.
Supplied Structures
The umbilical part of the left branch of the hepatic portal vein supplies nutrient-rich venous blood from the digestive tract.
