What are the functions of goblet cells

Options

A. Production of enzyme
B. Production of mucin
C. Production of hormone
D. Production of HCl

Explanation

### Step-by-Step Solution:

1. **Identify the Location of Goblet Cells**: Goblet cells are specialized epithelial cells primarily found in the lining of the gastrointestinal tract, including the stomach and intestines.

2. **Understand the Main Function**: The primary function of goblet cells is to produce mucus. This mucus plays a crucial role in protecting the epithelial lining of the stomach and intestines.

3. **Role of Mucus in Digestion**: The mucus secreted by goblet cells serves several purposes:
- It lubricates the intestinal contents, aiding in smooth passage through the digestive tract.
- It forms a protective barrier that prevents the acidic gastric juices (like hydrochloric acid) from damaging the stomach lining.
- It helps trap pathogens and particles, contributing to the immune defense of the gastrointestinal tract.

4. **Conclusion**: The main function of goblet cells is the production of mucus (or mucin), which is essential for protecting the digestive tract and facilitating digestion.

### Final Answer:
The functions of goblet cells include the production of mucus, which protects the epithelial lining of the stomach and intestines from harmful substances and aids in digestion.
