Question | Answer |
---|---|
albumin | plasma protein-maintains volume |
antibody | substance produced by the body that destroys or inactivates a specific substance (antigen) that has entered the body |
anticoagulant | substance preventing coagulation-antiprothrombin and antithromboplastin |
antigen | substance that, when introduced into the body, causes formation of antibodies against it |
basophil | white blood cell. Phagocytosis; releases heparin and histamine and promotes the inflammatory response |
coagulation | process of blood clotting |
diapedsis | passage of blood cells through unruptured vessel walls into tissues |
eosinophiles | white blood cell. increases during parasitic worm infestations and allergic attacks |
erythrocyte | red blood cell 4 - 5 million, with no nucleus |
erythropoiesis | formation of RBC's |
fibrin | insoluble protein which is converted into fibrin by the action of thrombin |
hemoglobin | oxygen carrying pigment of the blood |
hemolysis | the bursting of RBC's |
heparin | anticoagulant- slows bleeding |
leukocyte | white blood cell. 3,200 - 9,800 |
lymphocyte | white blood cell. helps form antibodies at the site of inflammation; protects against cancer. |
monocyte | white blood cell. phagocytosis |
neutrophil | white blood cell. phagocytosis against bacteria. Contributes to pus |
pathogenic | disease causing |
phagocytosis | process that surrounds, engulfs, and digests harmful bacteria. |
plasma | liquid portion of the blood |
platelets | responsible for blood clotting 250,000 - 450,000 |
prothrombin | a globulin that helps blood coagulate |
Rh Factor | Antigen found in RBC's |
serum | clear, pale yellow fluid that separates from a clot of blood plasma that contains no fibrinogen |
thrombin | enzyme found i blood; produced from an inactive precursor, prothrombin. inducing clotting by converting fibrinogen to fibrin. |
thrombocyte | platelet necessary for blood clotting |
thromboplastin | substance secreted by platelets when tissue is injured; necessary for blood clotting |
universal donor | type O blood; has no A or B antigens |
universal recipient | individual that has AB blood |
abscess | pus-filled cavity |
edema | excessive fluid in tissue |
erythroblastosis fetalis | hemolytic disease of a new born |
pus | product of inflammation; dead tissue, dead and living bacteria, dead WBC's, and blood plasma |
pyrexia | fever |
RHO gam | specific preparation of immune globulin given. |
