UNIT 3Module 8Ch17,18 VocabCh17: Immunological Disorders1.antibody deficiency→when few or no antibodies are produced (i.e selective IgAdeficiency or agammaglobulinemia)2.allergy→a heightened immune response (hypersensitivity) to an allergen, especially ofthe IgE type3.allergen→an antigen that is usually a harmless environmental substance that cause anallergy4.allografts→ exchanges between genetically different individuals belonging to the samespecies, most human transplants5.Arthus reaction→a localized hypersensitivity response caused by immune complexesand neutrophils characterized by severe pain, swelling and redness.6.asthma→an immediate respiratory allergy7.autoimmune disease→produced as a result of an immune reaction against body’s owntissues8.autograft→ tissue transplanted from one site on an individual’s body to another site onhis or her body9.degranulation→the release of mediators (i.e histamine) from a cell’s granules whichcause: capillary dilation, smooth muscle contraction and increased mucus secretion10. delayedtype hypersensitivity→caused by cytokines released from sensitized Tlymphocytes11. desensitization (hyposensitization)→ form of therapy for certain IgE mediatedallergies that involves injecting extremely small but increasing amounts of antigenregularly over a period of months directing the response from IgE to IgG12. DiGeorge syndrome→when the thymus fails to develop in the embryo, so T cells donot differentiate and absent in circulation13. disseminated intravascular coagulation (glomerulonephritis)→devastatingcondition in which the clot forms in small blood vessels leading to failure of vital organs14. Grave’s disease→organspecific autoimmune disease that affects the thyroid gland inwhich autoantibodies bind TSH receptor causing an overstimulation and enlargement(goiter) of the thyroid1
UNIT 3Module 8Ch17,18 Vocab15. Hay fever (allergic rhinitis) →marked by itching, teary eyes, sneezing and runny eyes16.Hemolytic disease of the newborn (erythroblastosis fetalis) →occurs when apregnant Rh women becomes sensitized (develop antibodies) to the Rh antigen duringchildbirth if she is carries a Rh+ baby.17. Hives (urticaria) →skin condition characterized by wheal and flare18. hypersensitivity→a heightened immune response to an antigen that injures tissue19. immunodeficiency→disorder that occurs when the immune system is too weak toprevent infection or too weak to mount a response against an antigen20. immunotherapy→technique that alters the immune response and can therefore be
