| Histamine | A compound that is released by cells in response to injury in in allergic and
inflammatory reaction causing contraction of smooth muscle and dilation of capillaries |
| Agranulocytes | also known as mononuclear leukocytes are white blood cells with a one lobe
nucleus characterized by the absence of granules in their cytoplasm which distinguishes them
from granulocytes |
| Monocytes | A large phagocytic White blood cell with a simple oval nucleus and clear grayish

| Hemolysis | The rupture or destruction of red blood cells |
| Leukemia | A progressive disease where the bone marrow and other blood forming organs
produce increased number of immature or abnormal leukocytes these suppress the production
of normal blood cells leading to anemia and other symptoms |
| Polycythemia | and abnormally increased concentration of hemoglobin in the blood through
either reproduction of plasma volume or increase in red cell numbers |
