Which gastric secretion is correctly matched with its source

Options

A. Pepsin-chief cells
B. Chymotrypsin-parietal cells
C. HCl-Goblet cells
D. Mucus-Oxyntic cells

Answer

To determine which gastric secretion is correctly matched with its source, we will evaluate each option based on the information provided in the video transcript.

### Step-by-Step Solution:

1. **Identify the gastric secretions and their sources**:
- Pepsin
- Chymotrypsinogen
- Hydrochloric acid (HCl)
- Mucus

2. **Evaluate Pepsin**:
- Pepsin is secreted by chief cells in the stomach.
- This statement is correct as per the information provided.

3. **Evaluate Chymotrypsinogen**:
- Chymotrypsinogen is mentioned to be secreted by parietal cells, which is incorrect.
- Chymotrypsinogen is actually secreted by the pancreas, not the stomach.

4. **Evaluate Hydrochloric Acid (HCl)**:
- HCl is stated to be secreted by goblet cells, which is also incorrect.
- HCl is secreted by parietal cells.

5. **Evaluate Mucus**:
- Mucus is said to be secreted by auxentic cells, which is incorrect.
- Mucus is actually secreted by goblet cells.

6. **Conclusion**:
- The only correctly matched secretion with its source is Pepsin, which is secreted by chief cells.

### Final Answer:
The correctly matched gastric secretion with its source is **Pepsin secreted by Chief Cells**.
