Which organ produces bile for fat digestion?

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

Answer: (B)

Fat digestion relies on bile to emulsify fats, increasing the surface area for enzymes to work. The liver is the organ that produces bile. Bile contains bile acids that break large fat globules into smaller droplets, making fat digestion more efficient. After production, bile is stored and concentrated in the gallbladder and released into the small intestine when fatty chyme arrives. The stomach mainly secretes acid and enzymes for protein digestion, the pancreas releases digestive enzymes and bicarbonate into the small intestine but does not produce bile, and the spleen is involved in immune function and blood filtration, not digestion. So, the liver is the source of bile.
