Where do bile and fat meet to emulsify fat?

• A. In the small intestine
• B. In the stomach
• C. In the liver
• D. In the large intestine

Answer: (A)

Bile and fat meet in the small intestine, specifically when fatty chyme arrives in the duodenum. Bile, produced by the liver and stored in the gallbladder, is released into the small intestine and contains bile salts that surround fat droplets. This emulsification breaks fats into much smaller droplets, increasing the surface area for pancreatic lipase to work. With a larger surface, fats are digested more efficiently into fatty acids and monoglycerides for absorption. The stomach doesn’t provide bile, the liver is where bile is made but not where emulsification occurs, and the large intestine isn’t involved in fat digestion.
