Which of the following statements is not correct'?

Options

A. Acini are present in the pancreas and secrete carboxy-peptidase
B. Brunner's glands are present i 'n the submucosa of stomach and secrete pepsinogen
C. Goblet cells are present in the mucosa of intestine and secrete mucus
D. Oxyntic cells are present in the mucosa of stomach and secrete HCl

Answer

To determine which statement is not correct, we will analyze each of the provided options step by step.

### Step-by-Step Solution:

1. **Analyze the First Option:**
- **Statement:** "Acini are present in the pancreas and secrete carboxypeptidase."
- **Explanation:** The acini (or pancreatic acini) are indeed the exocrine part of the pancreas and they secrete pancreatic juice, which contains the enzyme carboxypeptidase.
- **Conclusion:** This statement is **correct**.

2. **Analyze the Second Option:**
- **Statement:** "Brunner's glands are present in the submucosa of the stomach and secrete pepsinogen."
- **Explanation:** Brunner's glands are actually located in the submucosa of the duodenum (not the stomach) and they secrete an alkaline fluid, not pepsinogen. Pepsinogen is secreted by the chief cells in the stomach.
- **Conclusion:** This statement is **incorrect**.

3. **Analyze the Third Option:**
- **Statement:** "Goblet cells are present in the mucosa of the intestine and secrete mucus."
- **Explanation:** Goblet cells are indeed found in the mucosa of both the intestine and the stomach, and they secrete mucus.
- **Conclusion:** This statement is **correct**.

4. **Analyze the Fourth Option:**
- **Statement:** "Oxyntic cells are present in the mucosa of the stomach and secrete HCl."
- **Explanation:** Oxyntic cells, also known as parietal cells, are located in the gastric mucosa and they secrete hydrochloric acid (HCl).
- **Conclusion:** This statement is **correct**.

### Final Conclusion:
The statement that is not correct is the **second option**: "Brunner's glands are present in the submucosa of the stomach and secrete pepsinogen."
