01Isikhumbaukuzwela

Isikhumba esizwelayo siwuhlobo lwesikhumba esinenkinga, futhi kungase kube nesikhumba esibucayi kunoma yiluphi uhlobo lwesikhumba.Njengazo zonke izinhlobo zesikhumba zingase zibe nesikhumba esigugayo, isikhumba sezinduna, njll. Izicubu ezizwelayo zihlukaniswa kakhulu zibe ezakuzalwa nezizuziwe.Imisipha ezwelayo yokuzalwa i-epidermis emincane, imithambo yegazi esobala ku-dermis, nezihlathi eziminyene kalula futhi zivuvuke.Imisipha ebucayi etholiwe ibangelwa ukucindezeleka ngokweqile, ukuphila okungavamile kwansuku zonke, ukungcoliswa kwemvelo noma ukusetshenziswa ngokweqile kwemikhiqizo yokugcinwa kwe-asidi.

02 Izimpawu zesikhumba esibucayi

Isikhumba sincane, ama-capillary abonakala kalula, futhi kunemicu ebomvu.'Isikhumba sijwayele ukuguquguquka ngokungalingani;Ama-pores mahle futhi aqinile;Isikhumba somile futhi siphelelwe amanzi.Isikhumba esizwelayo siyisikhumba esintekenteke kakhulu.Kungakhathaliseki ukuthi ukunakekelwa kwesikhumba noma izimonyo, kuzodala ukucwayiza nokuluma ebusweni uma unganakile.

03 Izimbangela zokungezwani komzimba nezinto ezithile

1. Ukuhlanza ngokweqile: ngaphansi kwezimo ezijwayelekile, kwanele ukugeza ubuso bakho kabili ngosuku ngokuhlanza ubuso.Ngesikhathi esifanayo, ungagezi ubuso bakho ngamaphepha obuso amunca amafutha ahlukahlukene kanye nensipho yesandla.Uma uyisebenzisa kaningi, isikhumba sakho sizozwela ngenxa yokuhlanza ngokweqile.

2. Ukunakekelwa kwesikhumba ngokweqile: qaphela inani elifanele lokunakekelwa kwesikhumba, futhi ungasebenzisi imikhiqizo eminingi yokunakekelwa kwesikhumba enezithako eziyinkimbinkimbi nemiphumela eminingi, ngaphandle kwalokho izoshukumisa isikhumba sobuso futhi ibangele isikhumba senze isikhumba esibucayi.

3. Umswakama ongemuhle: uma isikhumba singenawo umswakama kahle ngemva kokunakekelwa kwesikhumba, kuzoholela ekulahlekelweni ngokushesha komswakama wesikhumba, futhi isikhumba sizoba sengozini yokushoda kwamanzi.Ngokuhamba kwesikhathi, isikhumba sizokwakha isikhumba esibucayi.

4. I-asidi yesithelo imhlophe: I-asidi yesithelo iyindlela evamile yokwenza mhlophe.Yenza isikhumba sibukeke sithambile futhi simhlophe ngokukhipha i-cuticle, kodwa i-cuticle iyifilimu evikelayo yokuvikela isikhumba ezintweni zangaphandle.Ngaphandle kwalolu ngqimba lokuvikela, isikhumba sizozwela kakhulu.

5. Imbangela yangaphakathi kanye nembangela yangaphandle: imbangela yangaphakathi ukungasebenzi kahle kwesikhumba kanye nokuphazamiseka kwe-endocrine, futhi imbangela yangaphandle ukuhlasela nokugqugquzelwa kothuli, amagciwane, ukudla, izidakamizwa kanye nezinye izinto ezine ezinkulu ezingezwani nomzimba.

Izici zemisipha ezwelayo

1. Kubonakala sengathi isikhumba sincane futhi siguquguqukayo, futhi igazi elibomvu ebusweni liyabonakala (ama-capillaries anwetshiwe).

2. Isikhumba sithambekele ekubeni bomvu nokushisa ngenxa yokushintsha kwezinga lokushisa.

3. Kulula ukuthintwa yizici zemvelo (thintana nemisipha ezwelayo, imisipha ezwela ububomvu, imisipha ezwela ukucindezeleka), izinguquko zonyaka kanye nokukhuthazwa kwemikhiqizo yokunakekelwa kobuso, ngokuvamile okubangelwa izici zofuzo, kodwa ngokuvamile ngenxa yokusetshenziswa izimonyo ze-hormonal eziholela esikhumbeni esibucayi, esingase sihambisane nokuzwela kwesikhumba okuhlelekile.

Emitholampilo yesikhumba noma izikhungo zobuhle, lapho sihlaziya izinkinga ezibucayi kumakhasimende, ngaphezu kokubuza amakhasimende nokubuka ngeso lenyama, singasebenzisa okunyeizinsimbi zokuxilonga isikhumbaukuqonda ngokunembe kakhudlwana izinkinga zesikhumba ezijulile futhi ubikezele izinkinga ezingaba khona, ukuze uthathe izinyathelo kusengaphambili ngaphambi kokwenza izinkinga ezingalungiseki
