Liver Structure

Liver Lobule

This looped animation shows the different ways of interpreting the cellular structure of the liver lobule. Liver animated cartoon.gif

Liver Blood Flow

Dual blood supply of the liver merges upon entry into the liver lobule at the portal field.

  2. branches of the hepatic artery

Hepatocytes

These are the adult functional cells forming the majority of the liver (80% of the cells).

Many different functions including:

  • Storage of substances including glucose (as glycogen), vitamin A (possibly in specialized adipocytes), vitamin B12, folic acid and iron.
  • Lipid Turnover synthesis of plasmalipoproteins
  • Plasma Protein Synthesis albumin, alpha and beta globulins, prothrombin, fibrinogen
  • Metabolism fat soluble compounds (drugs, insecticides), steroid hormones turnover
  • Secretion bile (about 1 litre/day)
