Saliva plays a role in both mechanical and chemical digestion.

1. **Mechanical Digestion:** Saliva helps moisten food, making it easier to chew and swallow. This is considered a mechanical process as it aids in the physical breakdown of food.

2. **Chemical Digestion:** Saliva contains enzymes, such as amylase, which begin the chemical breakdown of carbohydrates even before food reaches the stomach.

In summary, saliva contributes to both mechanical and chemical digestion.
