Question

Quizplus · Accepted Answer

Pernicious anemia is a type of macrocytic anemia caused by a decrease in vitamin B12 absorption due to a lack of intrinsic factor produced by the stomach. Aplastic anemia is a condition where the bone marrow doesn't produce enough new blood cells, sickle cell anemia is a genetic disorder where red blood cells become rigid and misshapen, and neither of these conditions are directly related to vitamin B12 absorption.
