Sonke sike saba nemibimbi evela eminweni nasezinzwaneni zethu lapho sicwiliswa emanzini isikhathi eside. Kufana nokuthi iminwe yethu isiphenduke umvini omisiwe futhi ayinamsebenzi.
Ngokuqinisekile wake wazibuza ukuthi kungani lokhu kwenzeka. Ososayensi banencazelo ngakho, futhi abanye bathi iyisibonelo sokuziphendukela kwemvelo okungenasici. Ngakho isizathu esenza sithole iminwe eshwabene emanzini olwandle kanye izibhuku zokubhukuda ingase ibe nokuhlobana kwayo nokuziphendukela kwemvelo.
Yile ndlela iminwe eshwabana ngayo ngaphansi kwamanzi
Isikhumba sinezingqimba eziningi. Ungqimba olungaphezulu lubizwa ngokuthi i-epidermis, futhi lulandelwa yi-dermis. Ungqimba olungaphansi kakhulu lubizwa nge-subcutaneous layer, lapho kutholakala khona imithambo yegazi emikhulu nemizwa, kanye nezicubu ezinamafutha nezixhumeneyo. I-epidermis iyashwabana lapho ibekwe emanzini isikhathi eside. Lapho ijula esikhunjeni, i-epidermis nayo ihlukaniswe yaba izingqimba ezine ezengeziwe: i-stratum corneum, i-granular layer, i-squamous cell layer, ne-basal cell layer.
I-Harvard Health Publishing iqinisekisa ukuthi imibimbi ivela engxenyeni engenhla ye-epidermis noma i-stratum corneum. Lolu ngqimba lufana nesipontshi esimunca amanzi lapho sicwiliswa emanzini. Iba thambile futhi iguquke ngokwengeziwe njengoba ikhula lapho ingaphansi kwamanzi isikhathi eside. Lokhu kunxephezela ukwenyuka kwevolumu yoketshezi futhi ungabuyela endaweni yakho yasekuqaleni.
Nokho, imibimbi ibonakala kakhulu eminweni, ezinzwaneni nasezintendeni zezandla ngoba i-stratum corneum ishubile kulezi zindawo uma iqhathaniswa nezinye izindawo zesikhumba. Futhi mayelana nenjongo engase ibe nayo, ososayensi baye basungula nezinkolelo-mbono ezithile, kuhlanganise nokuziphendukela kwemvelo komuntu.
Imibimbi ingavimbela ukushelela
Abanye abantu bangase babone le mibimbi njengengadingekile, kodwa lo mshini uyisibonelo sokuziphendukela kwemvelo komuntu.
Izinzwane zingashwabana ngisho noma zingacwiliswanga ekugezeni kwebhamuza. Iqiniso elilula lokuthi ukuhamba ungafake zicathulo otshanini obumanzi nobuswakama kuphinde kubangele ukuthi i-epidermis ishwabene kube sengathi icwiliswe emanzini. Ososayensi bathi akukhona nje ukusabela komzimba okulula. Kungenzeka ukuthi yaklanywa ngesizathu esihle kukho konke ukuziphendukela kwemvelo kwabantu.
Ezinye izifundo zithi i-epidermis yeminwe nezinzwane ishwabene izinto ezimbili. Okokuqala, bakhela iziteshi ukusiza ukukhipha amanzi. Okwesibili, yayiklanyelwe gwema ukushelela. Ngakho-ke manje sithola incazelo yokuthi kungani izingane eziningi zimelana nokuwa eduze konqenqema lwechibi.
Izinzwane ezimanzi ziyashintsha ukusuka kumathayi omjaho ukuya kumathayi esimo sezulu sonke anonyathela ukuze kudonseke. Ngokuqinisekile abakhiqizi bezicathulo namathayi bangafunda emakhonweni okuklama okuziphendukela kwemvelo bonke abantu abazuza kuwo.
