Which of the following statement is not correct?

Options

A. Acini are present in the pancreas and secrete carboxypeptidase
B. Brunner's glands are present in 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, let's analyze each of the provided statements step by step:

1. **Statement 1**: "Acini are present in the pancreas and they secrete carboxypeptidase."
- **Analysis**: Acini are indeed specialized cells found in the pancreas. They secrete digestive enzymes, including carboxypeptidase, which is involved in protein digestion. This statement is correct.

2. **Statement 2**: "Brunner's glands are present in the submucosa of the stomach and they secrete pepsinogen."
- **Analysis**: This statement is incorrect. Brunner's glands are located in the submucosa of the small intestine, not the stomach. They secrete an alkaline fluid that helps to neutralize gastric acid in the chyme. Pepsinogen is secreted by the chief cells in the stomach, not by Brunner's glands. Therefore, this statement is not correct.

3. **Statement 3**: "Goblet cells are present in the mucosa of the intestine and secrete mucus."
- **Analysis**: Goblet cells are indeed present in the mucosa of the intestine and are responsible for secreting mucus, which aids in digestion and protects the intestinal lining. This statement is correct.

4. **Statement 4**: "Oxynitic cells are present in the mucosa of the stomach and they secrete HCl."
- **Analysis**: Oxynitic cells, also known as parietal cells, are found in the mucosa of the stomach and are responsible for secreting hydrochloric acid (HCl). This statement is correct.

**Conclusion**: The statement that is not correct is Statement 2: "Brunner's glands are present in the submucosa of the stomach and they secrete pepsinogen."
