The organ that stores bile is the gall bladder.

• A. Gall bladder
• B. Appendix
• C. Spleen
• D. Liver

Answer: (A)

Bile storage and concentration occur in the gallbladder. Bile is produced by liver cells and flows into the gallbladder, where it is concentrated as water and other components are reabsorbed. When you eat a fatty meal, the hormone cholecystokinin signals the gallbladder to contract and release bile into the small intestine via the bile ducts to help emulsify fats. The liver makes bile but does not primarily store it, so it isn’t the best answer to “stores bile.” The appendix and spleen have other roles (immune and hematologic functions) and do not participate in bile storage or digestion.
