Imibuzo Eyisibonelo Ngama-Lymphocyte kanye Nempendulo Eqondile Yokuzivikela Emzimbeni. Ku-biology kanye nezokwelapha, ukuqonda ukuthi isimiso somzimba sokuzivikela sisebenza kanjani kubalulekile ekuqondeni ukuthi imizimba yethu ilwa kanjani nezifo nezifo ezahlukahlukene. Ingxenye ebalulekile yalesi simiso ama-lymphocyte, amangqamuzana amhlophe egazi adlala indima ebalulekile empendulweni ethile yokuzivikela komzimba. Lesi sihloko… Funda kabanzi

Imibuzo Yokuxoxisana Ngama-Phagocyte: Ama-Phagocyte awuhlobo lweseli elimhlophe legazi elidlala indima ebalulekile ohlelweni lokuzivikela komzimba. Lawa maseli anesibopho sokubhubhisa amagciwane ayingozi, njengebhaktheriya namagciwane, ngenqubo ebizwa ngokuthi i-phagocytosis. Kulesi sihloko, sizohlola umqondo we-phagocytosis ngokujulile futhi sinikeze imibuzo eminingana yokuxoxisana ukusiza... Funda kabanzi

Imibuzo Eyisibonelo Exoxa Ngezingxenye Zesistimu Yokuzivikela Yomzimba Uhlelo lokuzivikela lomzimba, olwaziwa kakhulu ngokuthi uhlelo lokuzivikela komzimba, luyindlela yezinto eziphilayo esetshenziswa izinto eziphilayo ukulwa nokutheleleka nezifo. Uhlelo lokuzivikela komzimba luvikela umzimba ezinhlobonhlobo zezifo ezibangelwa amagciwane, okuhlanganisa amabhaktheriya, amagciwane, isikhunta, kanye nezinambuzane. Ukuze uqonde kabanzi lolu hlelo, nansi eminye imibuzo eyisibonelo exoxa... Funda kabanzi

Imibuzo Nengxoxo Eyisibonelo: Impendulo Yomzimba Nokuqashelwa Komzimba. Uhlelo lomzimba luyinethiwekhi eyinkimbinkimbi yezitho zomzimba, amaseli, nama-molecule emzimbeni asebenza ndawonye ukuze asivikele ezifweni nasekuthelelekeni. Ukuqonda impendulo yomzimba nokuthi umzimba uqaphela kanjani izinto zangaphandle kubalulekile kubhayoloji kanye nezokwelapha. Kulesi sihloko… Funda kabanzi

Imibuzo Eyisibonelo Exoxa Ngokuzivikela Kwangaphakathi Okuqondile (i-Antigen-Antibody) Uhlelo lokuzivikela komzimba luyindlela eyinkimbinkimbi evikela umzimba ekuhlaselweni yizifo ezibangelwa amagciwane, njengebhaktheriya, amagciwane, kanye nezinambuzane. Kunezinhlobo ezimbili eziyinhloko zokuzivikela komzimba: ukuzivikela okungeyona into ethile (yemvelo) kanye nokuzivikela okuqondile (okuzivumelanisa nezimo). Ukuzivikela kwangaphakathi okuqondile, okwaziwa nangokuthi impendulo yokuzivikela komzimba eguquguqukayo, kuhilela amaseli e-B, amaseli e-T, kanye nokukhiqizwa kwama-antibody njenge... Funda kabanzi

Imibuzo Yesibonelo Sokuzivikela Kwangaphandle Okungaqondile Ukuzivikela kwangaphandle okungaqondile kungenye yezindlela zokuzivikela zomzimba ezidlala indima ebalulekile ekuvikeleni umzimba ezinsongweni ezahlukahlukene zezifo. Le ndlela yokuzivikela ivame ukubizwa ngokuthi ukuzivikela kwangaphakathi, okusebenza ngokuzenzakalelayo ukuvikela umzimba ekuthelelekeni ngamagciwane ngaphandle kokudinga noma yikuphi ukukhuthazwa okukhethekile kwangaphambilini. Kulesi sihloko, sizoxoxa ngemininingwane embalwa… Funda kabanzi

Imibuzo Eyisibonelo Exoxa Ngezinhlelo Zokuvikela Zangaphandle Nangaphakathi Isingeniso Uhlelo lokuvikela lukazwelonke luyinto ebalulekile ekugcineni ubukhosi nobuqotho besizwe. Lolu hlelo lungahlukaniswa ngezinhlobo ezimbili eziyinhloko: izinhlelo zokuvikela zangaphandle nezangaphakathi. Zombili zinezindima nemisebenzi ehambisanayo ukuqinisekisa ukuzinza nokuvikeleka kwesizwe. Lesi sihloko sizoxoxa ngezibonelo ze… Funda kabanzi

Umbuzo Wengxoxo Oyisibonelo: Ukuphazamiseka Ekushintshaneni Nokuthuthwa Kwezinto Ukushintshaniswa nokuthuthwa kwezinto emzimbeni kuyinqubo ebalulekile eqinisekisa ukuthi amangqamuzana ethu athola izakhamzimba ezidingekayo kanye nokususwa kahle kwemikhiqizo engcolile. Le nqubo ihilela izinhlelo ezahlukene zomzimba, okuhlanganisa nezinhlelo zokuphefumula, zenhliziyo, kanye nezokukhipha indle. Ukuphazamiseka kule nqubo kungaba nemiphumela emibi empilweni.

Imibuzo Nengxoxo Yezibonelo Ngenqubo Yokwakheka Komchamo Ezinso. Ukuqonda inqubo yokwakheka komchamo kubalulekile ekuqondeni uhlelo lokukhipha umchamo lomuntu. Izinso, njengezitho eziyinhloko kulesi simiso, zihlunga igazi, zisuse ukungcola, zigcine ibhalansi yoketshezi kanye ne-electrolyte, futhi zikhiqize ama-hormone abalulekile. Lesi sihloko sizoxoxa ngenqubo yokwakheka komchamo ngokuningiliziwe… Funda kabanzi

Imibuzo Eyisibonelo Exoxa Ngenqubo Yokushintshana Kwegesi Emaphashini Inqubo yokushintshana kwegesi emaphashini ingenye yemisebenzi ebalulekile yesistimu yokuphefumula yomuntu. Le nqubo ihilela ukungenisa umoya-mpilo emoyeni nokukhipha i-carbon dioxide egazini. Nazi ezinye zezibonelo zemibuzo ukukusiza uqonde ukuthi le nqubo isebenza kanjani ngokujulile.
