Where the parietal cells of the stomach is necessary for vitamin B12 absorption?
Parietal cells in the stomach are essential for vitamin B12 absorption because they produce intrinsic factor, a glycoprotein crucial for the absorption of vitamin B12 in the small intestine. When food enters the stomach, vitamin B12 binds to intrinsic factor, forming a complex that protects it from digestion. This complex is then absorbed in the ileum, the final part of the small intestine. Without intrinsic factor, vitamin B12 cannot be effectively absorbed, leading to potential deficiencies.

Why oral administration of vitamin B12 not effective as a treatment of pernicious anemia?
Pernicious anemia is due to a deficiency of a vitamin called intrinsic factor, which is normally produced by cells of the stomach. Intrinsic factor is required for the absorption of vitamin B12, so if intrinsic factor levels are insufficient, vitamin B12 will not be absorbed well. So administration of vitamin B12 will only help treat vitamin B12-deficiency anemia if vitamin B12 can be absorbed, and this can only happen if there are adequate levels of intrinsic factor to begin with. Patients with pernicious anemia do not have adequate intrinsic factor levels, so they will not be helped by vitamin B12 treatment since they can't absorb it well enough.
