Intrinsic factor is produced by which gastric cell type?

Explanation:
Intrinsic factor is produced by parietal cells in the stomach. These cells, also known as oxyntic cells, are responsible for secreting both hydrochloric acid and intrinsic factor. Intrinsic factor is a glycoprotein essential for the intestinal absorption of vitamin B12; it binds B12 in the stomach and forms a complex that is taken up in the terminal ileum. Without intrinsic factor, vitamin B12 cannot be efficiently absorbed, leading to pernicious anemia if deficiency persists. Chief cells release pepsinogen, G cells release gastrin, and mucous cells secrete protective mucus; none of these produce intrinsic factor.
