anemia
deficiency in erythrocytes or hemoglobin
aplastic anemia
failure of blood cell production in the bone marrow
hemolytic anemia
reduction in red cells due to excessive destruction
sickle cell anemia
hereditary disorder of abnormal hemoglobin producing sickle-shaped erythrocytes and hemolysis
thalassemia

pernicious anemia
lack of mature erythrocytes caused by inability to absorb vitamin B12 into the blood stream

excess iron deposits throughout the body
polycythemia vera

hemophilia
excessive bleeding caused by hereditary lack of factors VIII or IX necessary for blood clotting

leukemia
increase in malignant white blood cells
acute myeloid leukemia

acute lymphoid leukemia
