Answer:
Deficiency of Iron.
Step-by-step explanation:
Anemia is the generic name for a series of conditions characterized by a deficiency in hemoglobin concentration (an element of the blood that carries oxygen from the lungs to nourish all cells in the body) or in the production of red blood cells (the same as red blood cells or red blood cells).
They can be acute or chronic, acquired or hereditary. Adiquirides usually occur due to nutritional deficiency of iron, but in some cases may occur during pregnancy, due to a lack of vitamin B12 or folic acid (megaloblastic anemia).
