Hollow organ inferior to the liver designed to store and concentrate bile

                   Bile produced by liver hepatocytes is delivered by major excretory ducts
                   Sodium  is  actively  transported  out,  water  and  chloride  follow,  and  bile  is
                   concentrated
                   Bile is released in response to fats in the duodenum because of the action of
                   cholecystokinin

                   Sphincter  muscles  relax  and  gallbladder  contraction  forces  bile  into  the
                   duodenum
