38 Cards in this Set

  • Front
  • Back
albumin
protein in blood; maintains the proper amount of water in blood
antibody
protein (immunoglobulin) produced by lymphocytes in repsonse to bacteria, viruses, or other antigens. An antibody is psecific to an antigen and inactivates it
antigen
a substance (usually foreign) that stimulates the production of an antibody
basophil
granulocytic whit eblood cell with granules that stain blue when exposed to a basic dye
bilirubin
orange-yellow pigment in bile; formed by breakdown of hemoglobin when red blood cells die
coagulation
blood clotting
colony-stimulating factor (CSF)
protein that stimulates the growth and proliferation of white blood cells (granulocytes)
differentiation
change in structure and function of a cell as it matures; specialiation
electrophoresis
method of separating serum proteins by electrical charge
esoinophil
leukocyte with dense, reddish granule shaving an affirinity for red acidic dye; associated with allergic reactions
erythrocyte
red blood cell; 5 million per microliter (uL) or cubi milimeter of blood
erythropoietin (EPO)
hormone secreted by the kidneys that stimulates formation of red blood cells
fibrin
protein threads that form the basis of a blood clot
fibrinogen
plasma protein that is converted to fibrin in the clotting process
globulins
part of blood containing different plasma proteins; immunoglobings and alpha and beta globulins are examples
granulocyte
white blood cell with numerous dark-staining granules; eosinophil, neutrophil, and basophil
heme
iron-containing nonprotein portion of the meoglobin molecule
hemoglobin
blood protein containing iron; carries oxygen in red blood cells
hemolysis
destruction or breakdown of blood (red blood cells)
heparin
anticoagulant foudn in blood and tissue cells
immune reaction
response of the immune system to foreign invasion
immunoglobin
protein (globulin) with antibody activity; examples are IgG, IgM, IgA, IgE, IgD.
leukocyte
white blood cell
lymphocyte
mononuclear leukocyte that produces anitobdies
macrophage
monocyte that migrates from blood to tissue spaces; large phagocyte
megakaryocyte
large platelet precursor cell formed in bone marrow
mononuclear
pertaining to a cell (leukocyte) with a single round nucleus; lymphocytes and monocytes are mononuclear leukocytes
neutrophil
granulocytic leukocyte formed in bone marrow; phagocyte with neutral-staining granules; also called a polymorphonuclear leukocyte, or poly
plasma
liquid portion of blood; contains water, proteins, salts, nutrients, hormones, and vitamins
plasmapheresis
removal of plasma from withdrawn blood by centrifuge. Cells are retransfused into the donor. Fresh-frozen plasma or salt solution is used to replace withdrawn plasma
platelet
smallest blood cell (thrombocyte); clumps at sites of injury to prevent bleeding and facilitate clotting
prothrombin
plasma protein; converted to thrombin in the clotting process
reticulocyte
immature erythrocyte with a network of strands (reticulin) that can be seen after staining the cells with special dyes
Rh factor
antigen on red blood cells of Rh-positive individuals. The factor was first identified in teh blood of a rhesus monkey
serum
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 doe snto contain protein-coagulation factors
stem cell
bone marrow cell that vies rise to different tyeps of blood cells; hematopoietic stem cell
thrombin
enzyme that converts fibrinogen to fibrin during coagulation
thrombocyte
platelet
