Intrinsic factor is secreted by

Options

A. Goblet cells
B. Oxyntic cells
C. Argentaffin cells
D. Chief cells

Answer

**Step-by-Step Solution:**

1. **Understanding Intrinsic Factor**: Intrinsic factor is a glycoprotein that plays a crucial role in the absorption of vitamin B12 in the intestine. It is essential for the proper digestion and absorption of this vitamin, which is vital for red blood cell formation and neurological function.

2. **Identifying the Source**: The intrinsic factor is specifically secreted in the stomach. It is produced by certain specialized cells in the gastric mucosa.

3. **Identifying the Specific Cells**: The cells responsible for the secretion of intrinsic factor are known as parietal cells. These cells are also referred to as oxyntic cells. They are located in the gastric glands of the stomach lining.

4. **Conclusion**: Therefore, the intrinsic factor is secreted by the parietal cells, also known as oxyntic cells.

**Final Answer**: Intrinsic factor is secreted by oxyntic cells (parietal cells).
