Give one digestive function of the liver.

• A. Secretes mucous
• B. Bile production
• C. Absorbs water
• D. Digestive enzyme production

Answer: (B)

Bile production is the digestive function of the liver. Bile, made by liver cells, is released into the small intestine to emulsify fats, breaking large fat droplets into smaller ones to increase the surface area for digestive enzymes like pancreatic lipase to act more efficiently. Bile itself isn’t an enzyme; it works as a detergent to aid fat digestion and absorption.

The other options don’t fit because mucus is produced by the gut lining, not the liver; water absorption primarily occurs in the large intestine; and the digestive enzymes needed to break down nutrients are produced mainly by the pancreas and the lining of the small intestine, not by the liver.
