Which of the following gastric cells indirectly help in erythropoiesis?

Options

A. Goblet cells
B. Mucous cells
C. Chief cells
D. Parietal cells 2

Answer

To answer the question "Which of the following gastric cells indirectly help in erythropoiesis?", we can follow these steps:

### Step-by-Step Solution:

1. **Understand Erythropoiesis**: Erythropoiesis is the process of producing red blood cells (RBCs). It is essential for maintaining adequate oxygen levels in the body.

2. **Identify Gastric Cells**: The gastric glands contain several types of cells, including:
- Parietal cells
- Chief cells
- Goblet cells

3. **Function of Parietal Cells**: Parietal cells are responsible for secreting hydrochloric acid (HCl) and intrinsic factor. The intrinsic factor is crucial for the absorption of vitamin B12 in the intestines.

4. **Role of Vitamin B12**: Vitamin B12 is vital for the maturation of red blood cells. Without sufficient vitamin B12, RBCs cannot mature properly, leading to conditions such as pernicious anemia.

5. **Link Between Parietal Cells and Erythropoiesis**: Since parietal cells secrete intrinsic factor, which is necessary for the absorption of vitamin B12, they indirectly support erythropoiesis by ensuring that vitamin B12 is available for RBC maturation.

6. **Conclusion**: Therefore, the gastric cells that indirectly help in erythropoiesis are the **parietal cells**.

### Final Answer:
The correct answer is **Parietal cells**.
