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
