The gallbladder is part of the biliary system (with the liver and the bile ducts) and has the primary job of storing bile.   Humans can live without a gallbladder, the removal of the organ is called a cholecystectomy.   Some animals don’t even have a gallbladder to begin with; animals that graze or eat constantly, like the horse, do not have a gallbladder.    Humans eat few, larger meals, and require the bile in the gallbladder for a quick burst of digestive juices.

To find the gallbladder in the frog, lift the liver and look for a green colored pouch.   Bile from the gallbladder is delivered to the duodenum of the small intestine via the bile duct.
