Chapter.13&14 study guide

EosinophilWhite blood cell with reddish granules; numbers increase in allergic reactions
FibrinProtein threads that form the basis of a clot
ElecrophoresisMethod of separating out plasma proteins by electrical charge
AntigensForeign material that invades the body
Hematopoietic stem cellUndifferentiated blood cell
HeparinAnticoagulant found in the blood
PoikilocytosisDisorder of red blood cell morphology
NeutropeniaDeficiency in numbers of wbc’s
ErythroblastImmature red blood cell
MyeloidDerived from bone marrow
hemolysisBreakdown of recipients red blood cells when incompatible blood’s are mixed
Iron deficiency anemiaCondition associated with sideropenia, causing deficient production of hemoglobin
Hemolytic anemiaReduction in red blood cells due to excessive cell destruction
ThalassemiaInherited defect in ability to produce hemoglobin
Pernicious anemiaLack of mature blood cells due to inability to absorb vitamin B12 into the body
HemochromatosisExcessive deposits of iron throughout the body
HemophiliaExcessive bleeding caused by congenital lack of factor VIII or IX
Coagulation timeTest in which venous blood is clotted in a test tube
HematocritTest in which blood sample is spun in a test tube so that the red blood cells fall into the bottom and the percentage of rbc’s is determined
Red blood cell morphologyExamination of blood smear to determine the shape or form of cells
WBC differentialTest in which leukocytes are stained and counted under a microscope to see numbers of mature and immature forms
Erythrocyte sedimentation rateTest in which anticoagulant is added to a venous blood sample and the distance cells fall in the test tube over time is determined
AlbuminBlood protein that maintains the proper proportion and concentration of water in blood
EdemaSwelling;fluid leaks out into tissue spaces
ImmunoglobulinsIgM, IgG, IgA, IgD, and IgE
RelapseReturn of disease symptoms
PalliativeRelieving symptoms but not curing disease
LymphopoiesisFormation of lymph
Interstitial fluidFound in the spaces between cells and becomes lymph when it enters lymph capillaries
PlateletsIs NOT a component of the immune system
Bone marrowLymph nodes are NOT concentrated in this area
T-cellsHelper or suppressor cells
TonsilsOropharyngeal lymph tissue
ThymusMediastinal T-cell producer
AdenoidsNasopharyngeal lymph tissue
SpleenAbdominal organ that filters erythrocytes and activates lymphocytes
Bone marrowProduces lymphocytes and monocytes and all other blood cells
T-cell lymphocytesCytotoxic cells
Interferon & interleukinBest described as antiviral proteins produced by T-cell lymphocytes
LymphcytosisSlight increase in numbers of lymphocytes
ToxicPertaining to poison
Ct scanComputerized X-ray imaging in the transverse plane
HIVThe virus that causes AIDs
Hodgkin’s diseaseMalignant tumor of the lymph nodes
Herpes simplexViral infection causing blisters on skin of lips, nose, or genitals
Kaposi sarcomaCancer arising from the lining cells of capillaries, producing purplish skin nodules
Pneumocystis jiroveci (carinii) pneumoniaMajor lung infection with fever, cough, chest pain, and sputum treated with trimethoprim-sulfamethoxazole (septra, bactrim)
ToxoplasmosisProtozoal (parasitic) infection associated with Aids that may cause pneumonitis,hepatitis, and encephalitis
CryptococcosisFungal infection associated with AIDs involving brain and meninges, lungs, and skin
AtopyHypersensitivity or allergic state
Cell-mediated immunityAn immune response in which T-cells destroy antigens
T-cellsLymphocytes contained in the thymus gland that act on antigens
B-cellsLymphocytes that transform into plasma cells and secrete antibodies
Humoral immunityAn immune response in which B cells transform into plasma cells and secrete antibodies
