Which organ stores and concentrates bile produced in the liver?

• A. Gallbladder
• B. Liver
• C. Pancreas
• D. Small intestine

Answer: (A)

Bile storage and concentration is the function being tested. Bile is produced by liver cells and flows into bile ducts, but it’s the gallbladder that holds onto the bile between meals and concentrates it by absorbing water and electrolytes. This makes the bile more potent for emulsifying fats when released.

When a fatty meal enters the small intestine, hormones trigger the gallbladder to contract and push bile into the common bile duct, then into the duodenum to aid digestion. The other organs have different roles: the liver makes bile but does not store it; the pancreas provides digestive enzymes; the small intestine is where bile works rather than where it’s stored.
