Which organ produces bile?

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

Answer: (B)

Bile is produced by the liver. The liver’s hepatocytes synthesize bile, a digestive juice that contains bile acids, bilirubin, cholesterol, and phospholipids to help emulsify fats in the small intestine. After production, bile is stored and concentrated in the gallbladder and released into the duodenum when fatty chyme arrives. The other organs have different roles: the stomach uses acid and enzymes to break down food but doesn’t make bile; the spleen is involved in immune function and blood filtration; the pancreas produces pancreatic juice with enzymes and bicarbonate, not bile.
