Term | Definition |
---|---|
Agglutination | An immune response in which antibodies clump cells with specific antigens |
Clotting factor | An inactive chemical in the blood that, when activated, promotes a reaction cascade to form a clot |
Coagulation | Blood clotting; the third step in hemostasis |
Erythrocyte | Red blood cell |
Erythropoietin (EPO) | Chemical produced by the kidneys to stimulate red blood cell production when the oxygen blood level is low |
Fibrin | A solid protein fiber necessary for blood clot formation |
Fibrinogen | Protein dissolved in plasma that is the precursor to fibrin |
Formed elements | The cells and cell parts found in blood |
Granulocyte | Any of 3 types of leukocytes containing small granules that differ in color when stained (neutrophils, basophils, eosinophils) |
Hematocrit | A test that measures the percentage of erythrocytes to whole blood |
Hemocytoblast | A starting cell for the production of all the formed elements; stem cell |
Hemoglobin | A red, complex protein that is made of four chains of amino acids found in red blood cells and that functions to carry oxygen |
Hemopoiesis | Blood production (hemo-blood, poiesis-make) |
Hemostasis | 3 step process (vascular spasm, platelet plug formation, and coagulation) that stop bleeding |
Leukocyte | White blood cell 5 types (neutrophils, basophils, eosinophils, monocytes, lymphocytes) |
Lymphoid | Type of hemopoiesis that produces lymphocytes in lymphoid tissues outside the red bone marrow |
Myeloid | Type of hemopoiesis that produces all the formed elements in the red bone marrow |
Pluripotent | The ability to become cells of differing types. (Ex: hemocytoblast can become any one of eight different formed elements) |
Serum | Plasma with the fibrinogen and clotting factors removed |
Thrombocyte | One type of formed element of the blood; commonly called platelet |
