Which organ concentrates and stores bile?

Which organ concentrates and stores bile?

• A. Gallbladder
• B. Liver
• C. Pancreas
• D. Stomach

Answer: (A)

Bile is produced by the liver and then stored and concentrated in the gallbladder. The gallbladder removes water and electrolytes from the bile, making it more concentrated. When a fatty meal arrives, a release signal (cholecystokinin) prompts the gallbladder to contract and push bile into the duodenum through the common bile duct to help digest fats. The liver makes bile but does not store it long-term, the pancreas provides digestive enzymes, and the stomach stores and mixes food without handling bile.
