Bile is a greenish alkaline liquid which is stored in the

Step 1: Analyze the question The question asks where bile is stored, not where it is made. This difference is the key to the question.

Step 2: Explain the concept

• Bile is a greenish-yellow alkaline fluid. It is made by the liver.
• It contains bile salts, bile pigments (such as bilirubin) and cholesterol.
• Bile emulsifies fats, breaking large fat globules into tiny droplets. This gives lipase a larger surface area to work on. Its alkalinity also helps neutralise acidic chyme coming from the stomach.
• After it is made, bile travels through the hepatic duct to the gall bladder, a small pear-shaped sac under the liver. There it is stored and concentrated.
• When fatty food enters the duodenum, the gall bladder contracts and releases bile through the bile duct into the duodenum.

Step 3: Check each option

• A. Gall bladder: Correct. It stores bile.
• B. Liver: This is where bile is produced, not stored.
• C. Stomach: It secretes hydrochloric acid and pepsin, which are acidic, so it does not hold bile.
• D. Pancreas: It produces pancreatic juice (amylase, lipase, trypsin), not bile.

Step 4: Answer The correct option is A. gall bladder.

Exam tip: Remember "Liver Makes, Gall bladder Stores." If a question says produced or secreted, think liver. If it says stored, think gall bladder. JAMB often tests this distinction.
