Which of the following gastric cells indirectly help in erythropoiesis?

  1. Mucous cells
  2. Parietal cells
  3. Chief cells
  4. Goblet cells

Answer

(2) Parietal cells

Solution

As per NCERT, the parietal (oxyntic) cells of the gastric glands secrete HCl and the intrinsic factor, which is essential for the absorption of vitamin B12.

∵ Vitamin B12 is needed for the formation of RBCs (erythropoiesis)

∴ Parietal cells help in erythropoiesis indirectly.
