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]].
