Question

Which of the following gastric cells indirectly help in erythropoiesis ?

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

Answer 1

Answer: (A)

Parietal or oxyntic cell is a source of $HCl$ and intrinsic factor. $HCl$ converts iron present in diet from ferric to ferrous form so that it can be absorbed easily and used during erythropoiesis.
Intrinsic factor is essential for the absorption of vitamin $B_{12}$ and its deficiency causes pernicious anaemia.
