The process of erythropoiesis (the production of red blood cells)which 
takes place in the bone marrow can usually keep up with the normal daily 
replacement need of our bodies.  If however the destruction of red blood 
cells is greater than the bone marrow's production OR various nutrients 
needed for blood cell production are decreased (iron, B12, folate, other 
vitamins) then what results is a lower red blood cell count than normal 
which is called anemia.
