  1. Correct Answer – Option 3 : Parietal cells

    Concept:

    • Intrinsic factor is secreted by parietal cells of gastric glands in the stomach.
    • It helps in better absorption of Vitamin B12 from the ileum in the small intestine.
    • Vitamin B12 is necessary for red blood cells maturation. Inadequate intrinsic factor leads to vitamin B12 deficiency.
    • Vitamin B12 leads to pernicious anaemia.

    Explanation:

    Cheif cells Secretes pepsinogen
    Mucous cells Secretes alkaline mucus
    B cells Releases Y-shaped proteins called antibodies
