Vocabulary – Blood System
Question | Answer |
---|---|
Albumin: | Protein and blood; maintains the proper amount of water in the blood. |
Antibody (AB): | Specific protein (immunoglobulin) produced by lymphocytes in response to bacteria, viruses or other antigens. Antibody Pacific to an antigen and inactivates it. |
Basophil: | White blood cell containing granules that stain blue ; associated with the release of histamine and heparin |
Bilirubin: | Orange- yellow pigment in bile; or by the breakdown of hemoglobin when red blood cells are destroyed. |
Coagulation: | Blood clotting. |
Colony – stimulating factor (CFS): | Protein that stimulates growth of white blood cells (granulocytes). |
Differentiation: | Change in structure and function of the cell as it matures: specialization. |
Electrophoresis: | Method of separating serum protein by electrical charge. |
Eosinophil | White blood cell containing granules that stain red; associated with allergic reactions. |
Erythroblast: | Immature red blood cell. |
Erythrocyte: | Red blood cell. There are about 5 million per microliter (u L) or cubic millimeter (mm3) of blood. |
Erythropoietin (EP0): | Hormone secreted by the kidneys; stimulates red blood cell formation. |
Fibrin: | Protein that form the basis of a blood clot. |
Fibrinogen: | Plasma protein that is converted to fibrin in the clotting process. |
Globulin: | Plasma protein; alpha, beta, and gamma (immune) globulins are examples. |
Granulocyte: | White blood cell with numerous dark – staining granules: eosinophil, neutrophil, and basophil. |
Hematopoietic stem cell: | Cell in the bone marrow that gives rise to all types of blood cells. |
Hemoglobin: | Blood protein containing iron; carry oxygen in red blood cells. |
Hemolysis: | Destruction or breakdown of blood (red blood cells) if blood types are not compatible during transfusion. |
Heparin: | Anticoagulant found in blood and tissue cells. |
Immune reaction: | Response of the immune system to foreign invasion. |
Immunoglobulin: | Protein (globulin) with antibody activity; examples are IgA, IgM, IgG, IgE, IgD. Immun/o means protection. |
Leukocyte: | White blood cell. |
Lymphocyte: | Mononuclear leukocyte that produces antibodies. |
Macrophage: | Monocyte that migrates from the blood state. As a phagocyte, it engulfs material and debris. In the liver, spleen and bone marrow, macrophages destroy worn-out red blood cells. |
Megakaryocyte: | Large platelet precursor cell found in bone marrow. |
Monocyte: | Leukocyte with one large nucleus. It is felt that engulfs or in material and debris. Monocytes become macrophages as they leave the blood and enter body tissue. |
Mononuclear: | Pertaining to a cell (leukocyte) with a single round nucleus; lymphocytes and monocytes are mononuclear leukocytes. |
Myoblast: | Immature bone marrow that gives rise to granulocytes. |
Neutrophil: | Granulocytic leukocyte born in bone marrow. It is a phagocytic tissue fighting itself. Also called a Polymorphonuclear leukocyte. |
Plasma: | Liquid portion of blood; contains water, proteins, salts, nutrients, lipids, hormones, and vitamins. |
Plasmapheresis: | Removal of plasma from withdrawn blood by centrifuge. Collected cells are re-transfused back into the donor. Fresh frozen plasma or salt solution is used to replace withdrawn plasma. |
Platelet: | Small blood fragment that collects at site of injury to begin the clotting process |
Polymorphonuclear: | Pertaining to white blood cell with multi-loaded; neutrophil. |
Prothrombin: | Plasma protein; converted to thrombin in the clotting process. |
Reticulocyte | Immature erythrocyte. A network of strands (reticulin) is seen after staining the cells special dye. |
Rh factor: | Antigen on red blood cells of our Rh – positive (Rh*) individuals. The factor was first identified in the blood of a rhesus monkey. |
Serum | Plasma minus clotting proteins and cell. Clear, yellowish fluid that separates from blood when it is allowed to clot. It is born from plasma, but does not contain protein – coagulation factors. |
Stem cell: | Unspecified cell that gives rise to mature, specialized forms. A hematopoietic stem cell is the progenitor for all different types of blood cells. |
Thrombin: | Enzyme that converts fibrinogen to the fibrin and during coagulation |
Thrombocyte | Platelet. |
