Bimwe mu bintu bigira ingaruka ku minkanyari mu ruhu

Ubusobanuro bw'umwimerere bw'imiterere y'uruhu ni imiterere y'uruhu rwacu. Iherekezwa n'abantu igihe bavuka. Igizwe n'imirongo y'uruhu ihindagurika n'imirongo y'uruhu, ahanini ikaba ari poligoni zidahinduka kandi zidahinduka. Urebye neza uruhu rwambaye ubusa, ubona imiterere igoye kandi ihindagurika, ndetse n'umusatsi mwiza w'amabara akomeye cyangwa yoroheje. Ariko, uko igihe kigenda gihita, abantu bakomeza gusaza, kandi uruhu narwo rugenda rusaza buhoro buhoro. Muri icyo gihe, uruhu rukunze kugaragara ruzahura n'ibintu byo hanze nko kwanduza ibidukikije, kandi rugakomeza gukomereka, kandi igipimo cyo kwangirika kw'uturemangingo twa stratum corneum kizahinduka. Umubare w'imirongo y'uruhu n'imirongo y'uruhu urimo urahinduka, kandi imiterere ihamye nayo isa n'aho yahujwe, umubare uragabanuka, kandi ubuso bukomeza kwaguka, bityo uruhu rugahinduka iminkanyari kandi rugakomera.
Ubusanzwe, mbere y'imyaka 25, ubuso bw'uruhu buba bworoshye, burabagirana, kandi burushaho kuba bwiza. Nyuma y'ibyo ariko, uruhu rutangira gusaza buhoro buhoro kandi ibimenyetso by'umubiri bikunze guhinduka.
1. Ubushuhe bw'uruhu n'imbogamizi ku ruhu
Ubushakashatsi bwinshi ku ruhu rudakomeye bwibanda ku mikorere ya stratum corneum, nko gukora ku bushobozi bwo kubika amazi n'imikorere y'uruhu. Nk'inyigo y'ubushuhe, ibintu bifasha uruhu guhumeka neza, n'impinduka mu mikorere y'uturemangingo twa stratum corneum. Ubushuhe bugabanuka cyane, bigatuma uruhu ruhinduka nk'uruhu. Gutakaza uturemangingo tw'uruhu birahindagurika, bigatuma habaho uruhu rusa n'ururenda. Ubushuhe bw'uruhu bufitanye isano rya bugufi n'ubushuhe, ubwiza n'ubuto bw'uruhu. Ubushuhe bw'uruhu bugenda neza kandi bufite amazi menshi bwigaragaza buri gihe kugira ngo butange urumuri, mu gihe stratum corneum yumye kandi ifite ibisebe yigaragaza mu buryo butari ubwabyo butuma uruhu rusa n'imvi. Iyo uruhu rufite ubushuhe buke, uruhu ruba rwumye kandi rugakomera, kandi uruhu rukamera nk'urudakomeye.
Uruhu rufite imikorere mike y'uruzitiro rumeze nk'umutaka wacitse. Amazi yo mu mubiri ntabwo ahita ashira mu buryo bworoshye, ahubwo n'ibintu byo hanze biroroshye kwinjiramo, kandi no kubyimba bikunze kubaho. Nk'ibibazo by'uruhu bifitanye isano no kubyimba: gushwara, gushwara, gushisha, gushya, gutukura, n'ibindi. Ibibazo by'uruhu bigaruka bidaterwa n'ubwoko bw'uruhu ahubwo biterwa no kubyimba guhoraho mu ruhu.
Uturemangingo tw’inyuma tw’inyuma tw’inyuma twerekanye ko twatangiye gusana ububyimba iyo ibyangiritse byari byoroheje, naho twatangiye gucika intege iyo ibyangiritse byari bikomeye. Uturemangingo tw’urwego rw’ibanze twahinduwe n’uko twatangiye gucika intege, kandi hari umubare munini w’uturemangingo twa dyskeratotic.
2. Dermis itakaza uburibwe bwayo
Ubukonje bw'uruhu bufitanye isano rya bugufi no gukomera kw'uruhu. Ubukonje bw'uruhu buragabanuka, ubukonje bw'uruhu cyangwa iminkanyari bigaragara, kandi ubukonje bw'uruhu buriyongera. Fibroblast ni igice cy'ingenzi cyane mu ruhu kandi kigira uruhare runini mu gukora iminkanyari isohora impuzandengo n'uturemangingo tw'inyuma y'uruhu. Igira uruhare runini mu gusana ibikomere by'ingingo. Uko umuntu asaza, ubunini bw'uruhu buragabanuka uko umunkanyari ugenda ugabanuka buhoro buhoro. Gusaza k'uruhu biragaragara, bishobora kugaragara nk'uruhu rwumye kandi rudakomeye, iminkanyari yiyongera kandi yimbitse, uruhu rurerure, no kugabanuka k'ubukonje. Izabukuru ziherekezwa no kugabanuka kwa poroteyine nyinshi z'uruhu, kubura gukomera mu ruhu, no kwiyongera k'uburebure bw'uruhu bigatera kugaragara iminkanyari.
Mbere y'uko ibibazo by'uruhu bibaho, tuba dufite byinshi byo gukora. Urugero,isesengura ry'uruhubishobora kudufasha kugabanya umuvuduko cyangwa gukemura ibibazo by'uruhu ku rugero runaka mbere yuko ibibazo by'uruhu bigaragara neza!
