Question

Quizplus · Accepted Answer

Pernicious anemia is often associated with the destruction of parietal cells by an autoimmune mechanism, as these cells are responsible for the production of intrinsic factor, which is necessary for the absorption of vitamin B12. Without intrinsic factor, vitamin B12 cannot be absorbed, leading to pernicious anemia.
