Which one of the following types of cells and their secretion is correctly mathced?

Options

A. Oxyntic cells-a secretion with pH between 2.0 and 3.0
B. Alpha cells of lslets of Langerhans-secretion that decreases blood sugar level
C. Kupffer cells-a digestive enzyme that hydrolyses nucleic acids
D. none of these

Explanation

To solve the question "Which one of the following types of cells and their secretion is correctly matched?", we will analyze each option provided.

### Step-by-Step Solution:

1. **Analyze Option A: Auxentic Cells**
- Auxentic cells, also known as parietal cells, are located in the gastric lining of the stomach.
- Their primary function is to secrete hydrochloric acid (HCl).
- The pH of gastric acid is typically between 2 to 3, which is highly acidic.
- **Conclusion:** This option is correctly matched.

2. **Analyze Option B: Alpha Cells of Islet of Langerhans**
- Alpha cells are located in the pancreas and are responsible for secreting glucagon.
- Glucagon functions to increase blood sugar levels by promoting the conversion of glycogen to glucose in the liver.
- The statement claims that alpha cells decrease blood sugar levels, which is incorrect.
- **Conclusion:** This option is incorrectly matched.

3. **Analyze Option C: Kupfer Cells**
- Kupfer cells are specialized macrophages located in the liver.
- Their primary role is to phagocytize pathogens and dead cells, not to secrete digestive enzymes.
- They do not hydrolyze nucleic acids; hence, the statement is incorrect.
- **Conclusion:** This option is incorrectly matched.

4. **Analyze Option D: None of These**
- This option suggests that none of the previous options are correctly matched.
- However, since Option A is correctly matched, this option is also incorrect.
- **Conclusion:** This option is incorrectly matched.

### Final Answer:
The correct answer is **Option A: Auxentic cells secrete with pH 2 to 3**.
