What is the function of bile in the digestion of fats in the small intestine?
Anna35 [415]

Answer:

Bile is a fluid that is made and released by the liver and stored in the gallbladder. Bile helps with digestion. It breaks down fats into fatty acids, which can be taken into the body by the digestive tract.

Explanation:

When digesting fats, bile acts as an emulsifier to break the large fat globules into smaller emulsion droplets. Emulsified fats provide a larger area for the fat-digesting enzymes (lipase) to act, making the process quicker. Bile acts as a good solvent.
