| anemia |
deficient number of red blood cells or deficient hemoglobin |
| antibody |
substance produced by the body that destroys or inactivates a specific substance that has entered the body |
| antigen |
substance that, when introduced into the body, causes formation of antibodies against it |
| aplastic anemia |
blood disorder characterized by a low red blood cell count; caused by destruction of myeloid tissue in the bone marrow |
| basophil |
white blood cell that stains readily with basic dyes |
| buffy coat |
thin layer of white blood cells and platelets located between red blood cells and plasma in a centrifuged sample of blood |
| carbaminohemoglobin |
the compound formed by the union of carbon dioxide with hemoglobin |
| embolism |
obstruction of a blood vessel by forgein matter carried in the bloodstream |
| embolus |
a blood clot or other substance that is moving in the blood and may block a blood vessel |
| eosinophil |
white blood cell that is readily stained by eosin |
| erythroblastosis fetalis |
a disease that may develop when an Rh-negative mother has anti-Rh antibodies and gives birth to an Rh-positive baby and the antibodies react with the Rh-negative cells of the body |
| erythrocyte |
red blood cells |
| fibrin |
insoluble protein in clotted blood |
| fibrogen |
soluble blood protein that is converted to insoluble fibrin during clotting |
| hematocrit |
volume percent of blood cells in whole blood |
| hemoglobin |
iron-containing protein in red blood cells |
| hemorrhagic anemia |
condition charaterized by low oxygen carrying capacity of blood; caused by decreased red blood cell lifespan and/or increased rate of RBC destruction |
| heparin |
substance obtained from the liver; inhibits blood clotting |
| leukemia |
blood cancer characterized by an increase in white blood cells |
| leukocyte |
white blood cells |
| leukosytosis |
abnormally high white blood cell numbers in the blood |
| leukopenia |
abnormally low white blood cell number in the blood |
| lymphocyte |
type of white blood cell |
| macrophage |
phagocytic cells in the immune system |
| monocyte |
a phagocyte |
| neutrophil |
white blood cell that stains readily with neutral dyes |
| oxyhemoglobin |
hemoglobin combined with oxygen |
| pernicious anemia |
deficiency of red blood cells resulting from a lack of vitamin B12 |
| phagocyte |
white blood cell that engulfs microbes and digests them |
| plasma |
the liquid part of the blood |
| plasma protein |
any of several proteins normally found in the plasma; includes albumins, globulins, and fibrinogen |
| polycythemia |
an excessive number of red blood cells |
| prothrombin |
a protein present in normal blood that is required fo blood clotting |
| prothrombin activator |
a protein formed by clotting factors from damaged tissue cells and platelets; it converts prothrombin into thrombin, a step essential to forming a blood clot |
| serum |
blood plasma minus its clotting factors, still contains antibodies |
| sickle cell anemia |
when only one defective gene is inherited and only a small amount of hemoglobun that is less soluble than usual is produced |
| thrombin |
protein important in blood clotting |
| thrombocyte |
plays a role in blood clotting; also called platelet |
| thrombosis |
formation of a clot in a blood vessel |
| thrombus |
stationary blood clot |
