Term
ALBUMIN
Definition
Protein in the blood; maintains the proper amount of water in the blood
Term
ANTIBODY
Definition
Protein (immunoglobin) produced by lymphocytes in response to bacteria, viruses, or other anitgens. An anitbody is specific to an antigen and inactivates it
Term
ANTIGEN
Definition
Substance (usually foreign) that stimulates the production of an antibody
Term
BASOPHIL
Definition
Granulocytic white blood cell with granules that stain blue when exposed to a basic dye
Term
BILIRUBIN
Definition
Orange-yellow pigment found in bile. It is formed by the breakdown of hemoglobin when red blood cells die
Term
COAGULATION
Definition
Blood clotting
Term
COLONY-STIMULATING FACTOR (CSF)
Definition
Protein that stimulates the growth and proliferation of white blood cells (granulocytes)
Term
DIFFERENTIATION
Definition
Change in structure and function of a cell as it matures; specialization
Term
ELECTROPHORESIS
Definition
Method of separating serum proteins by electrical charge
Term
EOSINOPHIL
Definition
Granulocytic white blood cell with granules that stain red with the acidic dye eosin; associated with allergic reactions
Term
ERYTHROCYTE
Definition
Red blood cell. There are about 5 million per microliter or cubic millimeter of blood
Term
ERYTHROPOIETIN (EPO)
Definition
Hormone secreted by the kidneys that stimulates formation of RBC's
Term
FIBRIN
Definition
Protein threads that form the basis of a blood clot
Term
FIBRINOGEN
Definition
Plasma protein that is converted to fibrin in the clotting process
Term
GLOBULINS
Definition
Part of the blood containing different plasma proteins. Immunoglobulins and alpha and beta globulins are examples
Term
GRANULOCYTE
Definition
White blood cell with numerous dark-staining granules: eosinophil, neutrophil, and basophil
Term
HEME
Definition
Iron containing nonprotein portion of the hemoglobin molecule
Term
HEMOGLOBIN
Definition
Blood protein containing iron; carries oxygen in red blood cells
Term
HEMOLYSIS
Definition
Destruction or breakdown of blood (red blood cells)
Term
HEPARIN
Definition
Anticoagulant found in blood and tissue cells
Term
IMMUNE REACTION
Definition
Response of the immune system to foreign invasion
Term
IMMUNOGLOBULIN
Definition
Protein (globulin) with anitbody activity; examples are IgG, IgM, IgA, IgE, IgD. Immun/o means protection
Term
LEUKOCYTE
Definition
White blood cell
Term
LYMPHOCYTE
Definition
Mononuclear leukocyte that produces antibodies
Term
MACROPHAGE
Definition
Monocyte that migrates from the blood to tissue spaces. It is a large phagocyte
Term
MEGAKARYOCYTE
Definition
Large platelet precursor cell found in the bone marrow
Term
MONOCYTE
Definition
Large mononuclear phagocytic leukocyte formed in bone marrow. Monocytes become macrophages as they leave the blood and enter body tissues
Term
MONONUCLEAR
Definition
Pertaining to a cell (leukocyte) with a single round nucleus; lymphocytes and monocytes are mononuclear leukocytes
Term
NEUTROPHIL
Definition
Granulocytic leukocyte formed in bone marrow;a phagocyte with neutral-staining granules; also called polymorphonuclear leukocyte, or "poly"
Term
PLASMA
Definition
Liquid portion of blood; contains water, proteins, nutrients, salts, hormones, and vitamins
Term
PLASMAPHERESIS
Definition
Removal of plasma from withdrawn blood by centrifuge. Collected cells are retransfused back into the donor. Fresh-frozen plasma or salt solution is used to replace withdrawn plasma
Term
PLATELET
Definition
Smallest blood cell (thrombocyte); these cells clump at sites of injury to prevent bleeding and facilitate clotting
Term
PROTHROMBIN
Definition
Plasma protein; converted to thrombin in the clotting process
Term
RETICULOCYTE
Definition
Immature erythrocyte with a network of strands (reticulin) that are seen after staining the cell with special dyes
Term
RH FACTOR
Definition
Antigen on red blood cells of Rh-positive individuals. The factor was first identified in the blood of a rhesus monkey
Term
SERUM
Definition
Plasma minus clotting proteins and cells. Clear, yellowish fluid that separates from blood when it is allowed to clot. It is formed from plasma, but does not contain protein-coagulation factors
Term
STEM CELL
Definition
Unspecialized cell that gives rise to mature, specialized forms. A hematopoietic stem cell is the progenitor for all different types of blood cells
Term

THROMBIN

Definition
Enzyme that converts fibrinogen to fibrin during coagulation
Term
