Major utility of breaking up of food into small bits during chewing is

Options

A. to reduce suface area of the food eaten up
B. to increase surface area of the food eaten up
C. to make the food soluble.
D. to enjoy taste of food

Answer

**Step-by-Step Solution:**

1. **Understanding the Process of Chewing:**
- Chewing is the mechanical breakdown of food into smaller pieces by the teeth. This process is essential for effective digestion.

2. **Reduction of Food Size:**
- When food is chewed, it is reduced in size, which makes it easier to swallow. Smaller pieces are less likely to cause choking, as they can pass more easily through the esophagus.

3. **Increasing Surface Area:**
- Chewing increases the surface area of the food. A larger surface area allows digestive enzymes to access more of the food at once, facilitating better digestion.

4. **Mixing with Saliva:**
- During chewing, saliva produced by the salivary glands mixes with the food. Saliva contains enzymes that begin the process of digestion, particularly for carbohydrates.

5. **Formation of Bolus:**
- The chewed food mixed with saliva forms a soft mass called a bolus, which is easier to swallow and transport to the stomach.

6. **Facilitating Digestion:**
- By increasing the surface area and mixing with saliva, chewing ensures that food is more readily digested once it reaches the stomach and intestines.

7. **Conclusion:**
- The major utility of breaking up food into small bits during chewing is to increase the surface area of the food eaten, which enhances digestion.

**Final Answer:**
The major utility of breaking up food into small bits during chewing is to increase the surface area of the food eaten.
