The stomach secretion necessary for normal hemoglobin production of red blood cells is intrinsic factor.
Explanation:
The stomach wall contains a group of cells called parietal cells. These parietal cells produce a type of protein called intrinsic factor, which binds to the vitamin B12 released from food by stomach acids, and binded together the intrinsic factor and the vitamin B12 form a complex that helps on the absorption of vitamin B12 in the small intestine. Vitamin B12 is a fundamental factor on the production of red blood cells, being part of the immune system and acting on the process of antibodies to prevent anemia.
