Introduction
Structure
- Lies between the right medial and quadrate lobes of the liver
- Partly attached
- Partly free
Function
- Stores bile
- Concentrates bile by absorption through the folded mucosal wall
Innervation
- Parasympathetic nerves
Histology
- Highly folded mucosa
- Reduced submucosa
- No lamina muscularis
- Simple columnar epithelium
- No glands
Species Differences
Equine
- The horse has no gallbladder
Canine
- In some dogs, the gallbladder is so deeply embedded it makes contact with the diaphragm and contacts the parietal surface
Rodents
- Rats do not have a gallbladder
