Bimwe mubintu bigira ingaruka kumiterere yinkoni mu ruhu

Ubusobanuro busanzwe bwibiranga inyama nigihuru ni imiterere rusange yuruhu. Iherekejwe nibibazo byabantu bavuka. Igizwe no gukurura uruhu rwuruhu rwuruhu hamwe nuruhu, ahanini ahanini polygons hamwe no guhinduka. Urebye mu buryo butaziguye uruhu rwambaye ubusa, urashobora kubona imitekerereze, akajagari, kimwe n'imisatsi myiza y'amabara aremereye cyangwa yoroheje. Ariko, hamwe nigihe, abantu bakomeje gusaza, kandi uruhu runangira buhoro buhoro. Muri icyo gihe, uruhu rukunze kugaragara kandi ruzababara no guhindagurika kw'ibidukikije, kandi tugakomeza gukomereka, kandi igipimo cyangirika kuri selile corneum izahinduka. Umubare wuruhu hamwe nimisozi yuruhu irahinduka, nuburyo bukomeye bugaragara kandi bugaragara, umubare ukomeza kwaguka, bityo uruhu rukomeje kwaguka, nuko uruhu rukomeza kwaguka kandi rukabi.
Mubisanzwe, mbere yimyaka 25, hejuru yuruhu ni yoroshye, urumuri, na elastike. Nyuma yibyo, ariko, uruhu rutangiye gusangira buhoro buhoro ibimenyetso bya physiologiya bihinduka.
1. Ubushuhe bwuruhu hamwe ninzitizi zuruhu
Ibyinshi mubushakashatsi ku ruhu ruto rwibanda kumikorere ya Corneum ya Strum, nkibikorwa byubushobozi bwo kugumana amazi nigikorwa cya bariyeri yuruhu. Nk'ubushakashatsi bwubushuhe, ibintu bisanzwe mubi, hamwe nimpinduka za lipide hagati ya stratum corneum. Gutakaza kwishuka birakabije, bituma uruhu ruhinduka no gupima. Kumenagura selile yipiganwa ntibirimo kandi bikavamo umusaruro wa marruff n'umunzani. Ubushuhe bwuruhu bufitanye isano rya bugufi nubushuhe, kurasa nibyiza byuruhu. Amazi meza, menshi yamazi yerekana buri gihe kugirango akore urumuri rwikirere, mugihe cyumye, stratum corneum yerekana muburyo budatumvikana bukurura uruhu. Hamwe no gushungura mu ruhu, uruhu ruhinduka kandi ruto, kandi uruhu rutuje.
Uruhu hamwe nimikorere ya bariyeri ni nka Umbrella yacitse. Ntabwo amazi meza ahinduka byoroshye, ariko gukangura hanze biroroshye gutera, no gutwika nabyo biragaragara. Nk'ibibazo by'uruhu bijyanye no gutwika: kuvugurura, gukomera, gukuramo, gutukura, etc. Ibitekerezo by'uruhu byatewe mu ruhu.
Epidermis Epidermis yerekanye ko yasanaga cyane mugihe ibyangiritse byoroheje, na acaphy mugihe ibyangiritse bikabije. Ingirabuzimafatizo z'ibanze zahinduwe na Atypia igaragara, kandi hari umubare munini wa selile.
2. Dermis itakaza imbaraga zayo
Gukomera kwuruhu bifitanye isano rya hafi nuruhu. Uruhu rworoshye ruragabanuka, ubunebwe bwuruhu cyangwa imyumbati bugaragara, hamwe nuruhu rwuruhu rwiyongera. Fibroblasts nicyo kintu cyingenzi cya selile cyingenzi muri dermis cyuruhu ukagira uruhare runini muri synthesis ya fibre yintumwa hamwe na matrix ihanitse. Ifite uruhare runini mu gusana ibikomere. Hamwe n'imyaka, ubunini bwuruhu buragabanuka nkibiri muri filake mu ruhu rugabanuka buhoro buhoro. Gusaza kuruhu ni icyamamare, gishobora kugerwaho nuruhu rwumye kandi rutoroshye, rwiyongereye kandi rwiyongereyeho iminkanyari, uruhu rurekuye, rugabanuka. Imyaka iraherekejwe no kugabanuka kwuruhu rwa proter proteine, kubura gushikama muruhu, no kwiyongera kwibinyabuzima byuruhu biganisha ku myuka.
Mbere rero ibibazo byuruhu birashirwaho, turacyafite ibintu byinshi byo gukora. Kurugero, theGusesengura uruhuIrashobora kudufasha gutinda cyangwa gukemura ibibazo byuruhu kurwego runaka mbere yibibazo byuruhu bigaragara neza!
