Quizplus · Accepted Answer

Anemia can be caused by a deficiency in vitamin B12, which is required for the production of red blood cells. In order for Vitamin B12 to be absorbed in the small intestine, it requires intrinsic factor, which is secreted by the parietal cells in the stomach. Therefore, a lack of intrinsic factor would lead to a decreased absorption of vitamin B12 and subsequently cause anemia. HCl, lipase, bile, and amylase are all important digestive secretions, but they do not have a direct role in the absorption of vitamin B12.
