Four subunits combine to make abnormal hemoglobin
Abnormal hemoglobin molecules clump together, altering
shape of red blood cells. Abnormal cells carry reduced
amount oxygen.
To of compensate for reduced oxygen level, medullary
cavities of bones enlarge to produce more red blood cells.
Spleen enlarges to remove excessive number of red
blood cells.
Too few red blood cells in circulation results in anemia.
