Excoriation in stomach results into

Options

A. Emulsification of fats
B. Formation of chyme.
C. Damage to mucosa
D. Killing of microbes

Answer

### Step-by-Step Solution:

1. **Understanding Excoriation**:
- Excoriation refers to the damage or injury to the mucosal layer of the stomach. This layer is crucial for protecting the stomach lining from the acidic environment and digestive enzymes.

2. **Role of Mucosal Layer**:
- The mucosal layer contains goblet cells that secrete mucus. This mucus serves as a protective lining, providing lubrication and safeguarding the stomach from self-digestion due to its acidic content.

3. **Consequences of Mucosal Damage**:
- When the mucosal layer is damaged (excoriation), it can lead to various complications, including inflammation, ulceration, and increased susceptibility to infections.

4. **Evaluating the Options**:
- The question provides multiple options regarding the results of excoriation in the stomach:
- **Option 1**: Emulsification of fats – This is incorrect as emulsification is a separate digestive process.
- **Option 2**: Formation of chyme – This is also incorrect as chyme formation occurs due to the mixing of food with digestive juices, not directly due to excoriation.
- **Option 3**: Damage of mucosa – This is correct, as excoriation itself is defined as the damage to the mucosal layer.
- **Option 4**: Killing of microbes – While hydrochloric acid in the stomach does kill microbes, this is not a direct result of excoriation.

5. **Conclusion**:
- The correct answer is **Option 3: Damage of mucosa**, as excoriation specifically refers to the damage of the stomach's mucosal layer.
