The gall bladder stores bile produced in the [[Liver - Anatomy & Physiology|liver]]. Bile is important in the digestion of lipids.

The gall bladder forms as an outgrowth of the bile duct, as a secondary hollow at the posterior edge of the original hepatic rudiment. The gall bladder and the '''cyctic duct''' joins the common bile duct which enters the [[Duodenum - Anatomy & Physiology|duodenum]] at the major '''duodenal papillae''' (with the pancreatic duct) on the dorsal surface of the [[Duodenum - Anatomy & Physiology|duodenum]].

The gall bladder lies opposite the 8th intercostal space. It has the thinest layers of tunica muscularis.

'''Bovine'''

'''Bovine'''

The bovine gall bladder has the thickest layers of the tunica muscularis. The sheep have a less projecting gall bladder than cows. The gallbladder lies against the 10th or 11th rib.

*Highly folded mucosa

The gall bladder has a highly folded '''mucosa'''. It has a reduced '''submucosa''' and no '''lamina muscularis'''. The gall bladder has a simple columnar epithelium and no glands present.
