Liver

The liver is unique amongst all organs of the body for it is easy to recognize its distinct polyhedral shaped hepatic lobules which are the functional units of the organ. Each lobule is separated from the other by interlobular septa and has a central vein to which all the peripheral veins drain. In the periphery of the lobule is the portal triad consisting of portal vein , hepatic artery and the interlobular branch of bile duct. The bile duct collects bile from the bile canaliculi which are insinuated between the liver plates. Between the liver plates are the sinusoids. The liver plates form the parenchyma of the organ and they run from the central vein like spokes of  bicycle wheel. They contain hepatocytes or liver cells.

The hepatic lobules are divided into three main zones

  • Centrilobular zone which surrounds the central vein
  • Intermediate zone
  • Periportal zone which surrounds the portal triad.
