Cov qe ntshav dawb ua haujlwm hauv ob txoj kev; lawv tau ingest los yog engulf kab mob thiab rhuav tshem los ntawm kev zom lawv. Cov qe ntshav dawb tuaj yeem ua tau kuj tsim cov tshuaj tiv thaiv kab mob kom rhuav tshem tshwj xeeb kab mob los ntawm clumping lawv ua ke thiab rhuav tshem lawv. Lawv kuj tsim cov tshuaj antitoxins uas tawm tsam cov co toxins uas tso tawm los ntawm kab mob.
Tsis tas li, ua li cas lub cev tiv thaiv kab mob puas tsuaj?
Cov tiv thaiv kab mob teb rau antigens los ntawm kev tsim cov cell uas ncaj qha tawm tsam kab mob , lossis los ntawm kev tsim cov protein tshwj xeeb hu ua tshuaj tiv thaiv kab mob. Antibodies txuas rau lub antigen thiab nyiam cov cell uas yuav engulf thiab rhuav tshem cov kab mob . Cov hlwb tseem ceeb ntawm kev tiv thaiv kab mob yog lymphocytes hu ua B cells thiab T cells.
Ib tus kuj tseem yuav nug tau tias, cov qe ntshav dawb nkag mus rau cov kab mob dab tsi? Phagocytes yog cov qe ntshav dawb uas yog attracted rau kab mob thiab muab txuas rau lawv. Thaum lawv tau txuas nrog lub kab mob , cov phagocyte ntawm tes membrane nyob ib puag ncig kab mob thiab engulfs nws. Qhov no txhais tau tias kab mob raug coj mus sab hauv ntawm phagocyte.
Tib neeg tseem nug, lub cev tiv thaiv kab mob li cas?
Koj lub cev siv cov qe ntshav dawb los sib ntaus tshem tawm cov kab mob thiab kab mob uas ua rau koj lub cev thiab ua rau koj mob. Cov qe ntshav dawb tau nyiam cov kab mob vim tias cov protein hu ua cov tshuaj tiv thaiv tau cim cov kab mob rau kev puas tsuaj. Cov tshuaj tiv thaiv kab mob no tshwj xeeb rau cov kab mob ua rau muaj kab mob thiab kab mob.
Cov qe ntshav dawb ua lub luag haujlwm twg hauv lub cev tiv thaiv kab mob?
Ntshav dawb . Cov qe ntshav dawb (tseem hu ua cov leukocytes los yog lub cev tiv thaiv kab mob ) yog hlwb uas tsim ib feem ntawm cov ntshav . Lawv pab tiv thaiv lub cev tiv thaiv kab mob sib kis thiab cov khoom siv txawv teb chaws raws li ib feem ntawm tiv thaiv kab mob.

Txoj kev kho mob qog noj ntshav twg siv cov phiaj tsom ntawm lub zog ionizing txhawm rau rhuav tshem cov hlwb phem?
Kev kho hluav taws xob lossis kho hluav taws xob, feem ntau sau luv RT, RTx, lossis XRT, yog kev kho mob siv hluav taws xob ionizing, feem ntau yog ib feem ntawm kev kho mob qog noj ntshav kom tswj lossis tua cov kab mob phem thiab nquag xa los ntawm cov kab nrawm
Dab tsi ua kom muaj peev xwm ntawm cov kab mob pathogenic ua rau muaj kab mob?
Cov kab mob virulence pab cov kab mob kom (1) nkag mus rau tus tswv tsev, (2) ua rau muaj kab mob, thiab (3) zam tus tswv tsev tiv thaiv. Exotoxins: Exotoxins suav nrog ntau hom kab mob protein thiab cov enzymes tsim thiab/lossis zais los ntawm cov kab mob pathogenic. Cov pawg loj suav nrog cytotoxins, neurotoxins, thiab enterotoxins
Ua li cas lymphocytes rhuav tshem cov kab mob?
Lymphocytes. Lymphocytes yog lwm hom qe ntshav dawb. Lawv paub cov proteins ntawm cov kab mob hu ua antigens. Yog tias lawv ua, lawv clone lawv tus kheej thiaj li tsim tau cov tshuaj tiv thaiv kom txaus los rhuav tshem cov kab mob
Vim li cas cov hlwb hauv MM Tumors raug rhuav tshem los ntawm kev tiv thaiv kab mob?
MM yog tshwm sim los ntawm qhov ua tsis tau zoo ntawm cov protein nyob hauv cov cell ntawm daim nyias nyias. Cov cell hauv MM qog tuaj yeem raug rhuav tshem los ntawm kev tiv thaiv kab mob
Cov kua ntshav ntshav yog dab tsi tom qab cov qe ntshav thiab cov ntshav khov tau raug tshem tawm?
Cov ntshav yog cov kua ntshav tom qab cov qe ntshav thiab cov protein sib xyaw tau raug tshem tawm. cov pa roj ntshav suav nrog oxygen, carbon dioxide, thiab nitrogen
