Cov kev tiv thaiv kab mob tiv thaiv lub cev los ntawm tejzaum nws muaj teeb meem tshuaj los ntawm kev paub thiab teb rau antigens. Antigens yog cov tshuaj (feem ntau yog cov protein) nyob saum cov cell, kab mob, kab mob, lossis kab mob . Cov tiv thaiv kab mob paub thiab rhuav tshem, lossis sim rau rhuav tshem, tshuaj uas muaj antigens.
Tsis tas li ntawd, lub cev twg tiv thaiv lub cev los ntawm cov kab mob?
Lub cev tiv thaiv kab mob thiab ntshav hlwb . Yog tias cov kab mob nkag mus rau ntawm daim tawv nqaij lossis cov mucous membranes, txoj haujlwm tiv thaiv lub cev hloov mus rau koj lub cev tiv thaiv kab mob. Koj lub cev tiv thaiv kab mob yog ib lub network nyuaj ntawm hlwb , cov cim qhia, thiab kabmob uas ua haujlwm ua ke los pab tua cov kab mob uas ua rau kis mob.
Lub cev peb txoj kab tiv thaiv kab mob yog dab tsi?
Muaj peb kab ntawm kev tiv thaiv : thawj yog kom cov neeg tawm tsam tawm (los ntawm daim tawv nqaij, daim nyias nyias, thiab lwm yam), qhov thib ob kab tiv thaiv muaj txoj hauv kev tshwj xeeb los tiv thaiv tiv thaiv kab mob uas tau tawg los ntawm thawj kab tiv thaiv (xws li nrog cov lus teb thiab ua npaws).

Antigens, tseem hu ua immunogens, yog cov lwg me me uas qhib kev tiv thaiv kev tiv thaiv
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
