Gallbladder.
Step-by-step explanation:
The gallbladder is an organ located under the liver that intervenes in food assimilation by the organism. Its main function is to store bile - a liquid produced by the liver to dissolve fats -. The liver produces bile and it reaches the gallbladder through the hepatic and cystic ducts, and it is stored in the gallbladder until it is needed. Whenever the stomach or intestine are digesting food, the gallbladder release the bile which flows through the cystic duct and the bile duct to the thin intestine. In fact, the secretion of bile by this organ is stimulated by food ingestion, especially by the ingestion of meat or fats.
