Lobules of liver
Lobules of Liver
The Lobules of Liver (pronunciation: /ˈlɒbjʊlz ɒv ˈlɪvər/) are the functional units of the liver, each consisting of millions of hepatic cells, or hepatocytes.
Etymology
The term "lobule" is derived from the Latin word "lobulus", meaning "a small lobe". The term "liver" comes from the Old English "lifer", which is of Germanic origin.
Structure
Each lobule is hexagonal in shape and consists of plates of hepatocytes radiating outwards from a central vein. The corners of the hexagon are formed by portal triads, each consisting of a branch of the hepatic artery, portal vein, and bile duct.
Function
The primary function of the lobules is to process the blood that flows through the liver, removing toxins and producing bile. The hepatocytes in the lobules perform various metabolic, secretory, and endocrine functions.
