Options

A. Mastication of food
B. Facilitation of swallowing
C. Help in the secretion of glucagon
D. Both (1) & (2)

Answer

**Step-by-Step Solution:**

1. **Understanding the Buccal Cavity**: The buccal cavity, commonly referred to as the mouth, is the initial part of the digestive system where food enters.

2. **Mastication of Food**: One of the primary functions of the buccal cavity is mastication, which is the process of chewing food. This is facilitated by the teeth, which break down food into smaller pieces, making it easier to digest.

3. **Salivary Glands and Enzyme Secretion**: The buccal cavity contains salivary glands that secrete saliva. Saliva contains an enzyme called salivary amylase, which begins the digestion of carbohydrates (specifically starch) in the mouth.

4. **Formation of a Bolus**: The saliva not only aids in the digestion of starch but also moistens the food, allowing it to combine with the saliva to form a soft mass known as a bolus. This is essential for swallowing.

5. **Facilitation of Swallowing**: The combination of saliva and food makes it easier to swallow, allowing the bolus to move smoothly down the esophagus into the stomach.

6. **Conclusion**: Therefore, the major functions of the buccal cavity include:
- Mastication of food (chewing)
- Secretion of salivary amylase for starch digestion
- Formation of a bolus for easy swallowing

**Final Answer**: The major functions of the buccal cavity are both mastication of food and facilitation of swallowing.
