What is the role of stomach in digestion?

The stomach churns and mixes food with digestive juices, breaking it down into a semi-liquid form called chyme.

How do enzymes aid in digestion?

Enzymes help to speed up chemical reactions in the digestive process, breaking down carbohydrates, proteins, and fats into smaller molecules.

What is the function of bile in digestion?

Bile aids in the digestion and absorption of fats by emulsifying them into smaller droplets.
