Histology

  • Polyhedral and angular cells
  • Larger cells than in mammals
  • Large, spherical nucleus
  • Base of cell forms a wall of the sinusoid
  • Cell apices communicate with the bile canaliculi
  • Granular cytoplasm
  • Liver cords form columns around the interlobular bile capillary. The cell arrangement is simpler than in mammals.
  • Sinusoids anastamose freely
  • Kupfer cells present
  • Reticular fibres support the liver cords
  • Elastic fibres in the capsule and vessels
