How is through chewing of food helpful in digestion?

Explanation

**Step-by-Step Solution:**

1. **Introduction to Chewing**: Chewing is the mechanical process of breaking down food into smaller pieces using our teeth. This is the first step in the digestive process.

2. **Breakdown of Food**: When we chew food properly, it breaks down larger food molecules into smaller ones. This increases the surface area of the food, making it easier for enzymes to act on it later in the digestive process.

3. **Reducing Stress on the Esophagus**: Properly chewed food reduces the stress on the esophagus. Larger food pieces can cause discomfort and difficulty when swallowing, while smaller pieces can be swallowed more easily.
