Tsis muaj kev tiv thaiv yog ib yam uas twb muaj lawm hauv lub cev. Kev tiv thaiv kev tiv thaiv yog tsim nyob rau hauv lus teb kom raug ib yam khoom txawv teb chaws. Thaum ua haujlwm tawm tsam ib hom antigen tshwj xeeb, tus kev tiv thaiv tseem nyob thoob plaws lub neej.
Tsis tas li ntawd, dab tsi yog innate thiab adaptive tiv thaiv muaj nyob rau hauv?
Cov lub cev tsis muaj zog yog li ntawd nws tuaj yeem ua haujlwm rau ob qho tib si induce thiab suppress kam rau ua. Cov ntsiab lus ntawm yoog raws teb kuj txhawb kev ua haujlwm ntawm cov lub cev tsis muaj zog qhov system. Piv txwv li, cov tshuaj tiv thaiv zais cia los ntawm B hlwb khi rau macrophages thiab lwm yam phagocytes los ntawm kev cuam tshuam nrog Fc receptors ntawm cov hlwb.
Tsis tas li ntawd, cov hlwb twg koom nrog hauv lub cev thiab kev tiv thaiv kab mob? Ntau yam ntawm hlwb hauv lub cev tsis muaj zog system (xws li dendritic hlwb , macrophages, mast hlwb , neutrophils, basophils thiab eosinophils) tsim cytokines lossis cuam tshuam nrog lwm yam hlwb ncaj qha nyob rau hauv thiaj li yuav qhib lub adaptive tiv thaiv kab mob qhov system.
Hauv qhov no, qhov txawv ntawm innate thiab adaptive immunity quizlet yog dab tsi?
Adaptive tiv thaiv kab mob muaj peev xwm lees paub ntau yam kab mob microbial thiab tsis kis kab mob thiab tsim tshwj xeeb tshwj xeeb tiv thaiv kab mob lus teb rau txhua yam khoom. Whereas, lub cev tsis muaj zog cov kab ke tsuas tuaj yeem lees paub cov txheej txheem sheared los ntawm chav kawm ntawm cov kab mob me me.
Dab tsi yog 5 kauj ruam hauv kev tiv thaiv kab mob?
Cov kauj ruam hauv cov txheej txheem tiv thaiv kab mob
- Cov Kauj Ruam Hauv Cov Lus Teb 1. Monocytes "noj" cov kab mob 2. Qhia tawm ib feem ntawm antigen ntawm cov xov tooj ntawm tes 3. Tus txais tos ntawm tus pab T-cell txheeb xyuas cov antigen 4.
- STEPS IN ADAPTIVE RESPONSE 5. Killer T-cells dhau los ua kom tua cov kab mob tshwj xeeb 6. B-cells dhau los ua haujlwm thiab tsim cov tshuaj tiv thaiv 7.

Dab tsi yog qhov sib txawv thiab qhov zoo sib xws ntawm cov khoom sib tsoo thiab qhov kov zoo?
Dab tsi yog qhov sib txawv thiab qhov zoo sib xws ntawm 'crude' kov thiab 'nplua' kov qhov hnov? Nyuaj kov yog hais txog kev nkag siab los ntawm kev txhawb nqa ntawm cov neeg txais khoom ntawm qhov tsis nkag siab nrog cov teb loj. Hauv kev sib piv, kev kov zoo yog hais txog cov neeg txais khoom ntawm kev nkag siab siab nrog cov chaw txais me me
Kev tiv thaiv kab mob thiab kev tiv thaiv kab mob yog dab tsi?
Lub cev tiv thaiv kab mob yog lub network nyuaj ntawm cov cell thiab cov protein uas tiv thaiv lub cev tiv thaiv kab mob. Lub cev tiv thaiv kab mob khaws cov ntaub ntawv ntawm txhua tus kab mob (microbe) nws tau swb lawm yog li nws tuaj yeem lees paub thiab rhuav tshem cov kab mob sai sai yog tias nws nkag mus rau hauv lub cev dua
Dab tsi yog qhov sib txawv ntawm kev tiv thaiv kab mob hauv lub ntsws thiab txwv?
Qhov txawv ntawm Obstructive thiab RestrictiveLung Disease. Lub sij hawm obstructive ntsws kab mob muaj xws li cov xwm txheej uas cuam tshuam ib tug neeg lub peev xwm los exhale tag nrho cov pa tawm ntawm lawv lub ntsws. Cov neeg uas muaj lub ntsws mob ntsws muaj kev nyuaj nyuaj nthuav dav lawv lub ntsws
Cov kab mob sib koom ua ke twg yog tus cwj pwm los ntawm kev sib koom ua ke ntawm kev txav mus los thiab kev sib koom ua ke ntawm qhov hnyav ntawm cov pob qij txha uas feem ntau yog relieved los ntawm so?
Osteoarthritis feem ntau cuam tshuam rau txhais tes, qis nraub qaum, caj dab, thiab hnyav sib koom tes xws li hauv caug, lub duav, thiab ko taw
Kev sib raug zoo ntawm lub cev xeeb tub thiab lub cev tiv thaiv kab mob yog dab tsi?
Thaum lub cev tiv thaiv kab mob los ntawm lub cev tam sim ntawd, qhov kev tiv thaiv kev tiv thaiv kab mob tsis yog. Txawm li cas los xij, cov txiaj ntsig ntawm kev hloov lub cev tiv thaiv kab mob yog qhov ntev ntev, tshwj xeeb heev, thiab muaj kev txhawb nqa mus ntev los ntawm kev nco T hlwb
