The Liver Lobule

An idealized representation of the "classical" liver lobule is a six-sided prism about 2 mm long and 1 mm in diameter. It is delimited by interlobular connective tissue (only little, if any, visible in humans; plentiful in e.g. pigs). In its corners we find the portal triads. In cross sections, the lobule is filled by cords of hepatic parenchymal cells, hepatocytes, which radiate from the central vein and are separated by vascular sinusoids.

There are other ways of dividing the parenchyma of the liver into units. Two common ways are divisions into portal lobules and liver acini.

• Portal lobules emphasize the afferent blood supply and bile drainage by the vessels of the portal triads. The secretory function of the liver is emphasized by the term liver acinus.
• Acini are smaller units than portal or "classical" liver lobules and relate structural units to terminal branches formed by the vessels of the portal triad but not the portal triad itself. Representations of portal lobules and liver acini vary in different textbooks.
