Sei tichivhenekera meso edu?
Sevana, vazhinji vedu takanga tichitisana nharo nevanin'ina kana shamwari. Inguva yakareba sei iwe waigona kubatisisa kuti uone pasina kumira? Maziso ako akatanga kupisa uye mvura uye pakupedzisira wakasiya.
Kuchenesa ndicho chiito chinokurumidza chokuvhara nekuzarura majwaira ako. Kuchenesa kunokosha nokuti inogadzirisa guruva guru uye inogadzirisa ziso reziso.
Ivhareji blink inotora anenge 400 milliseconds, asi iyo inogona kugadziriswa nezvinhu zvakawanda zvakadai sekuneta, kushandiswa kwemishonga, uye humwe hutano huripo. Kunyangwe iwe zvichida usingazvioni, munhu wega wega anotsvaira kamwe kamwe pamaminitsi gumi. Uropi hwemunhu hunogona kukanganwa rima rekuzununguka, richitibvumira kuva nemaonero anoenderera enyika.
Sezvambotaurwa pamusoro, chikonzero chikuru chemaziso edu anonyangarika ndekupukuta nekudzoka zvakare firimu rekuchema. Ifirimu redu rekuchema ndiro chaizvoizvo rakaoma uye rinogadzirwa zvinopfuura mvura. Misodzi yedu inoumbwa kunyanya mvura, mafuta uye mucus. Uyewo, kune mazana emamwe zvimwe zvikamu zvakadai semarosisomesiti anoshanda semishonga inorwisa mabhakitiriya. Kunewo mishonga yakawanda uye amino acids inobatsira kuderedza masero ari mu cornea, yakajeka, dome-kufanana sangano mberi kweziso.
Kunze kwekuchengeta maziso edu akafukidzwa, firimu yedu yemabvuro zvakare:
- inobatsira kuumba inenge yakakwana, yakanyatsooneka yepamusoro pamusoro pekonoa kuti chiedza chiise zvakanaka
- inobatsira kuendesa okisijeni kubva kumhepo kusvika ku cornea , sezvo pasina mutezo weropa kuti uununure zvakananga
- inodzivirira hutachiona hunokonzerwa nekuvapo kwe lysozym uye mamwe maantimicheni anonzi antibacterial
- ishes away debris
- inopa nzira yemasero machena eropa apo pane kukuvadzwa kumusoro
Kune zvipembenene zvakawanda zvemarudzi akasiyana-siyana mumhizha. Apo ziso rinosvinura, kune kumira kunomesa nzira iyo inoratidzira izvi gland kuti iite zvakavanzika zvemisodzi. Ikoko kunewo kishoma kaduku kakakosha kwechikoyi chinoputira mabhirikiti ku puncta , firimu inobvarura ichidhonza pipe.
Saka, kugadzirisa kunoratidzika secho chikonzero chikuru chatinonyorera. Zvisinei, masayendisiti akafukura zvimwe zvikonzero nei tichigona kunya kazhinji. Nyanzvi yezvematongerwe enyika inotaura kuti tinobhenekera kupfuura izvo zvinodiwa kuti tivezve patsva firimu yekuchema. Chimwe chidzidzo chakagadzirwa nemasayendisiti muna 2012 chinoratidza kuti tinogona kuvhenekera kune zvimwe zvikonzero.
Mushure mokuongorora tsvakurudzo yakawanda, vatsvakurudzi vakaona kuti iyo nguva chaiyo patinenge tanyunguduka haisi kuitika. Vakanyatsoona kuti tinopenya panguva dzisingatarisirwi. Semuenzaniso, pakuverenga, vanhu vakawanda vakavhenekera pamagumo emutsara. Apo munhu ari kuteerera mutauro, vanoedza kunongedza apo mukurukuri anomira pakati pemashoko. Imwe muenzaniso ndeyokuti vanhu vari kutarisa vhidhiyo, ivo vose vanowanzosvinura kana chiito pavhidhiyo chichikwira kwechinguva.
Inotora zvishoma zvakaoma, asi masayendisiti akafunga kuti tinoshandisa kubwinya semukana wekuti tive nepfungwa shomanana yokuzorora mupfungwa iyo inokurumidza kuvhara maitiro anooneka kuitira kuti tikwanise kuisa pfungwa dzedu pane zviripo.
Musayendisiti akawana kuti kana vanhu vakanyangarika, basa repfungwa rinowanikwa mune dzimwe nzvimbo muuropi dzinoshanda kana pfungwa iri mukunzorora kwakasimba. Vaifunga kuti kushandiswa kwechikamu ichi cheuropi kunoshanda sepfungwa shoma shoma iyo yakabvumira kutarisisa zvakanyanya apo maziso akazarurwa zvakare.
Vamwe vakaisa pachena kuti tinosvinura kune zvimwe zvikonzero zvepfungwa zvakare. Ongororo yakawedzerwa inodiwa asi inoratidzika zvakajeka kuti mamiriro edu epfungwa anochinjwa patinenge tanyungurudza uye kwete kungoerekana tatanga firimu rekuchema.
