Fibrinogen | Plasma protein that is converted to fibrin in the clotting process. |
Globulins | Major blood proteins; immunoglobulins, alpha, beta and gamma globulins are examples. |
Granulocyte | White blood cell with numerous dark-staining granules; neutrophil, eosinophil and basophil. |
Granulocytopenia | Deficiency of granulocytes. |
Hematopoiesis | Formation of blood cells. |
Hemoglobin | Blood protein containing iron; carries oxygen in red blood cells. |
Hemoglobinopathy | Disease or defect of hemoglobin production. Sickle cell anemia is an example. |
Hemolysis | Destruction or breakdown of blood; specifically red blood cells. |
Hemostasis | Stoppage of bleeding or circulation of blood. |
Heparin | Anticoagulant found in blood and tissues. |
Hypochromic | Pertaining to deficiency in color; decrease in hemoglobin in red blood cells. |

Immunoglobulin | Antibody-containing protein in the blood; IgA, IgG, IgM, |
Leukapheresis | Mechanical separation of white blood cells from the rest of the blood. |
Leukocyte | White blood cell. |
Leukocytopenia | Deficiency of white blood cells. |
Lymphocyte | White blood cell with a single nucleus (mononuclear); capable of producing antibodies. |
Macrocytosis | Presence of large red blood cells in the blood. |
Macrophage | Large phagocytic cell migrating from the blood into tissues. |
Megakaryocyte | Large, giant cell with a big nucleus; platelet precursor found in the bone marrow. |
Microcytosis | Increased numbers of smaller than normal red blood cells. |
Monoblast | Immature monocyte. |
Monocyte | White blood cell (agranulocyte) with one large nucleus; enter tissues as macrophages. |
Mononuclear | Pertaining to a white blood cell with a single, round nucleus; monocyte or lymphocyte. |
Morphology | Study of the shape and form of cells, particularly red blood cells. |
Myeloblast | Immature granulocytic while blood cell; a cell normally only found in the bone marrow. |
Myeloid | Derived from bone marrow. |
Myelogenous | Pertaining to cells produced in the bone marrow. |
Myelopoiesis | Formation and development of bone marrow or cells that originate from it. |
Neutropenia | Deficiency of neutrophils. |
Neutrophil | White blood cell with dark granules that stain with a neutral dye; phagocyte formed in the bone marrow and the body’s first line of defense against disease. |
Neutrophilia | Increased numbers of neutrophils. |
Pancytopenia | Deficiency of all (blood) cells. |
Phagocyte | Cell that engulfs another cell or foreign organism and destroys it. |
Plasma | Liquid portion of blood containing proteins, water, salts, nutrients, hormones and vitamins. |
Plasmapheresis | Removal of plasma from withdrawn blood by centrifuge. |
Platelet | Clotting cell or thrombocyte. |
Plateletpheresis | Separation of platelets from the rest of the blood. |
Poikilocytosis | Variation in the shape of red blood cells. |
