Blood, Lymph, and Immune System

anaphylaxis Exaggerated,life-threatening hypersitivity reaction to a previously encountered antigen.
antibody Proteins that are the most inportant weapon of the immune system.
antigen Substance that is recognized as harmful to the host and stimulates the formation of antibodies.
celluar immunity Acquired specific resistance,mediated by T cells,that produces reactive substances or directly exerts a cytotoxic effect on a cell that is identified as harmful.
host Organism in or on which anothe(usually parasitic)organism is nourished and harbored.
humoral immunity Aquired specific resistance(B cells) that produces antibodies that bind to and dispose of antigens.
immunocompentent Able to develop an immune response; able to recognize antigens and respond to them.
immunopathology Study of disease associated with overreactivity or underreacitivity of the immune response.
opportunistic infection Infection occurring in a person with a weakened immune system and caused by a microorganism that normally would not bring about the disease.
palliative treatment Treatment that provides relief, but not a cure.
serum Liquid portion of the blood that remains after the removal of fibrinogen.

anisocytosis Condition of marked variation in the size of erythrocytes.
ascites Accumulation of serous fluid in the peritoneal or pleural cavity.
bacteremia Presence of viable bacteria circulating in the bloodstream,considered "travelers"rather than blood infection.
hemolysis Destruction of RBC's with a release of hemoglobin that diffuses into the surrounding fluid.
hemostasis Arrest of bleeding or circulation.
immunity State of being protected against infection.
active immunity Immunity developed as a consequence of exposure to an antigen. (vaccination injection)
passive immunity Immunity in which antibodies formed in one individual are transfered to another.(to infant from mothers milk).
lymphadenopathy Any disease of the lymph nodes.
lymphosarcoma Malignant neoplasm disorder of lymphatic tissue. Non-Hodgkin disease.
septicemia Blood infection
serology Blood test to detect the presence of antibodies,antigens,immune substances.
titer Blood test that measures the amount of antibodies in blood,commonly used as an indicator of immune status.
APTT activated partial thromboplastin time Test that screens for deficiencies of some clotting factors,valuable for preop screening for bleeding tendencies.
blood culture Test to determine the presence of pathogens in the bloodstream.
CBC complete blood count Series of tests that include hemoglobin;hematocrit;RBC,WBC,and platelet counts;differential WBC count;RBC indices; and RBC and WBC morphology.
differential count Test that enumerates the distribution of WBCs in a stained blood smear by counting the different kinds of WBCs and reporting each as a percent of the total examined.
ERS (sed rate) erythrocyte sedimentation rate Measurement of the distance RBCs settle in 1 hour when whole blood is placed in a narrow tube.
HgB,Hb hemoglobin Measurement of the amount of hemoglobin found in a whole blood sample.
Hct hematocrit Measurement of the percentage of packed RBCs in a whole blood sample.
monospot Serlolgical test performed on a blood sample to detect the presence of a nonspecific antibody.
PT prothrombin time Test used to evaluate portions of the coagulation system and indirectly measure prothrombin.
RBC indices Mathematical calculation of the size, volume and concentration of hemoglobin for an average red blood cell.
Schilling test Test used to assess the absorption of radioactive vitamin B12 by the GI system.
lymphadenography Radiographic exam of lymph nodes after injection of a contrast medium.
lymphangiography Radiographic exam of lymph nodes or tissues after injection of contrast medium in the lymph vessels.
aspiration Draw in or out using suction.
bone marrow aspiration Procedure using a syringe with a thin aspirating needle that is inserted (usually the sternum or pelvic bone) to withdrawl a small sample of bone marrow fluid for microscopic evaluation.
biopsy Representative tissue sample removed from a body site for microscopic exam and diagnosis.
sentinel node biopsy Removal of the first lymph node(sentinal node)that receives drainage from cancer-containing areas and the one most likely to contain malignant cells.
bone marrow biopsy Removal of a small core sample of tissue from bone marrow for exam under a microscope.
lymphangiectomy Removal of a lymph vessel
transfusion Injecting of blood or blood components into the bloodstream.
autologus transfusion Transfusion prepared from recipient's own blood.
homologous transfusion Transfusion prepared from another individual whose blood is compatible with that of the recipient.
transplation Grafting of living tissue from its normal position to another site or from one person to another.
autologus bone marrow transplation Harvesting,freezing,and reinfusing the patient's own bone marrow.
homologus bone marrow transplation Transplantation of bone marrow from one individual to another.
