Which organ secretes bile to emulsify fats?

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

Answer: (B)

Bile production by the liver provides the essential emulsifying agents that break large fat droplets into smaller ones, increasing the surface area for pancreatic enzymes to work. The liver manufactures bile and sends it through bile ducts to the gallbladder, where it’s stored and concentrated until fatty chyme arrives in the small intestine. When fat enters the duodenum, signals trigger bile release into the intestine to emulsify fats. The gallbladder’s job is storage and concentration, not secretion, and the stomach does not produce bile while the pancreas secretes pancreatic juice for digestion.
