Quizplus · Accepted Answer

Pernicious anemia can occur when the stomach has been removed because it is the primary site of intrinsic factor production, which is necessary for the absorption of vitamin B12. It can also occur when the terminal ileum has been removed, as this is where vitamin B12 is absorbed. Additionally, a deficiency of intrinsic factor can lead to pernicious anemia, regardless of any surgical procedures. Therefore, all of the above factors can contribute to the development of pernicious anemia, making choice D the correct answer.
