Which cells secrete hydrochloric acid in the stomach?

Original practice item, not a recalled exam question. Nothing here is recorded.

The answer and the reasoning

B. Parietal cells

The relevant Gastrointestinal physiology principle makes Parietal cells the best answer because it directly explains the structure or physiological response in the stem.

Option by option

  • A. Chief cells

    Chief cells does not correspond to the structure or response being tested.

  • B. Parietal cells (correct)

    Correct. Parietal cells directly follows from the core gastrointestinal physiology relationship.

  • C. Goblet cells

    Goblet cells is associated with a different anatomical or physiological role.

  • D. Paneth cells

    Paneth cells is not supported by the key clue provided in this item.
