Pepsinogen is secreted from :

Options

A. argentaffin cells
B. goblets cells
C. chief cells
D. parietal cells

Answer

**Step-by-Step Solution:**

1. **Understanding Pepsinogen**: Pepsinogen is an inactive precursor of the enzyme pepsin, which is important for protein digestion in the stomach.

2. **Identifying the Source of Secretion**: To determine where pepsinogen is secreted from, we need to look at the different types of cells present in the stomach.

3. **Evaluating Options**:
- **Option 1: Urgent Affine Cells**: These cells are not responsible for secreting pepsinogen. They are identified by their staining properties and do not play a role in protein digestion.
- **Option 2: Goblet Cells**: Goblet cells are known for secreting mucus, which protects the lining of the gastrointestinal tract. They do not secrete pepsinogen.
- **Option 3: Chief Cells**: Chief cells are located in the gastric glands of the stomach and are responsible for secreting pepsinogen. This is the correct answer.
- **Option 4: HCL and Intrinsic Factor**: While hydrochloric acid (HCl) and intrinsic factor are important in the stomach, they do not secrete pepsinogen. HCl activates pepsinogen into pepsin.

4. **Conclusion**: The correct answer is that pepsinogen is secreted from Chief Cells.

**Final Answer**: Pepsinogen is secreted from Chief Cells.
