PORTAL TRACT [1 record]

English

Subject field(s)
  • Liver and Biliary Ducts
CONT

The liver has been described as a collection of units called lobules, each of which contains, in its centre, a branch of the hepatic vein and, in its outer areas, a complex known as a portal tract. The portal tract includes a bile duct, a small branch of the portal vein, and a branch of the hepatic artery.

CONT

The hepatic lobules are small structural units of the liver enclosed by a thin layer of connective tissue formed by the branches of the Glisson's capsule. Where several lobules join, the connective tissue is more abundant and encloses a blood vessel, vein, nerves, lymphatic vessels, and small bile ducts. The structures together with the connective tissue form the "portal canals".
