Structure
- 2 lobes
- Dark brown coloured
- Right lobe larger than left lobe
- Ventral and caudal to the heart
- CLosely associated to the proventriculus and spleen
- Thin capsule
- Indistinct lobation
Function
- See liver funtion
Vasculature
Innervation
Lymphatics
- See liver lymphatics
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
