Iindleko zezinyembezi
Iingqungquthela ezibini zeengcawa zifumaneka phezulu kwinqanaba leyeliso ngalinye (phantsi kwekhosidi) ngokubhekiselele. Kuzo, ngokwenene, inxalenye yamanzi yezinyembezi iveliswa (oku malunga ne-98%). Kwiimisele ezikhethekileyo, iinyembezi zivela kwi-conjunctiva, apho "zicebise" nge-mucus kunye namafutha, nazo zibonakala ngokubunjwa kwamaconsi amabi. Ukuma ngaphandle kwepilisi elahlayo, "amanzi esetyuwa" ahanjiswa ngokufanayo phezu kwamehlo kunye ne-blink nganye. Ukugqithiselwa kwayo kunye neinyembezi ezizalisekile imisebenzi yazo (oko kukuthi, ukuhlanjululwa) kuphuma kwiinqwelo zengqungqelo ekhoneni elingaphakathi kweso, okuthi, ngokukhawuleza, idibaniswa nesigxina somsi. Yingakho, xa sikhala, iphuma kumpumlo. Ngokuqhelekileyo ukugqabhuka kweengcambu zeso linye zivelisa ukusuka kwi-0.5 ukuya kwi-1 ml yamanzi ngosuku. Nangona kunjalo, ukuphulwa kwimeko yengqondo yomntu kunye nezinye izifo kuya kunceda ukutshintsha ezi zikhombisi. Ngoko, i-pea yezinyembezi iqulethe ezintathu: i-mucinous (mucous), i-liquid kunye ne-lipid (i-fat). Uluhlu oluphantsi lwe-mucosal "isiseko" salo lonke ifilimu (i-mucins ibonkco ebalulekileyo phakathi kwe-epithelium kunye ne-liquid). Emanzini - i-microelements (i-sodium, i-calcium, ion i-chlorine, njl njl. Njl.) Ziyachitheka, zenze iinyembezi zintyatyambo, kunye nezinye izinto ezixabisekileyo (i-albumin, i-lysozyme, i-immunoglobulin A), ezinika iipropthi ze-antimicrobial. Ubuncwane obuphezulu - i-thinnest yamanqatha - iyancipha ukwanda kwamanzi. Ngendlela, ukwenziwa kweekhemikhali zezinyembezi kufana nokubunjwa kwegazi, kwaye bayathwala ulwazi oluninzi. Nge "ifomula" yezinyembezi "ungafunda" imeko yobudala kunye nengqondo yomntu, kwaye ufumane izifo ezininzi. Ngokomzekelo, ii-oculists zase-Australia zifumana izifo ezithintekayo kwiintlungu zabantu abahluphekileyo kwesi sifo, iprotheni ekhethekileyo "yomhlaza" ifunyenwe.
Amanzi aphilayo
Kwiso ilinomdla, kufuneka lihlale lihlanjululwa. Ukongezelela "ukunkcenkceshela," ukuhlabalala okanye ukuphelelwa lithemba kukuqinisekisa ukutya okupheleleyo kwe-cornea kunye ne-oxygen saturation, ukubonakalisa "ukuhlaselwa" kwezinto ezincinci, ukuhlamba "imveliso" yezinto ezibalulekileyo kunye neentoni ezihlukahlukeneyo. Konke oku kunokwenzeka kuphela xa i-liquid isasazwa ngokugqithiseleyo phezu kwamehlo ngenxa yokunyuka kweentloko zeentloko, ukukhumbuza ukuhamba kweemoto zomoya. Ngethuba lokulila, ukuphefumula okufutshane kunye nokunyuka kwexesha elide (ukuqeqeshwa kweenkqubo zokujikeleza kunye nokuphefumula), ukuphefumula kuzinzileyo - kunye nokuphumla okulungileyo (njengoko emva kokuzikhandla ngokomzimba) kuqinisekisiwe. Ukongeza, imfihlo yezinyembezi iqulethe izinto zengqondo ezinciphisa iimvakalelo zokuxhatshazwa kunye nokuxhalabisa (ngezinyembezi umzimba uyingxenye kunye nama-hormone angaphezu kwama-"volley"). Ngokwenzululwazi yaseMelika, ukubunjwa kwezinyembezi kuxhomekeke kwisizathu sokuchitha. Eyona mileyo, ininzi kakhulu, i-salty iyintlungu kunye nokuphelelwa lithemba. Bafumene iiprotheyini ezininzi kunye nezinto ezikhethekileyo zeekhemikhali ezenziwe ngexesha loxinzelelo. Kunobungozi ukugcina olo "luhle". Ukuphazamiseka okubi kungabangela ukuphazamiseka kwenkqubo yeentlanzi, izifo zesifo senhliziyo, isilonda kunye nomhlaza. Akuyona ingozi ukuba amadoda "angalili" ahlala kwiminyaka emibini engaphantsi kweminyaka. Ngoko khala impilo! Ngokwezibalo, ama-74% amabhinqa kunye nama-20% amadoda akhala ngaphandle kwezinyembezi, ngokulandelanayo, ama-36% kunye nama-25%, ama-36% kunye nama-25% ngokulandelanayo, 41% kunye ne-22% yothando kunye namava ahlobene. I-71% yabesifazane kunye ne-40% yamehlo bathambekele ekubambeni ngomsebenzi wobugcisa. Iimpawu ezinkulu kwihlabathi, ngokutsho kootitshala baseDatshi, iiChileans (kwindawo yesibini - abaseMerika abesifazana, kwintombi yesithathu - eTurkey). Abesifazane baseUkraine kule ndawo ngesizathu esithile akukho ... Nangona ukukhala kwe Yaroslavna yethu kwaye ngaphandle kwayo kukho iingcamango. Iinyembezi ezibangelwa intlungu yomzimba zi-analgesics. Ziqukethe izinto eziphilayo ezizenza njenge-morphine. Ukongezelela, lukhuselo olunamandla lwe-antibacterial kunye ne-anti-antial - iinyembezi zatyhila i-lysozyme enzyme, ebulala ama-95% amabhaktheriya kwimitha emi-5-10. Ngako oko, kwisiko sasendulo ukuhlamba amanxeba amabutho, iinyembezi zazingenangqiqo.
Kutheni bengakhali?
Ngokomyinge, umntu uhlala malunga neelitha ezingama-70 zezinyembezi zobomi. Kukholelwa ukuba ubulili obuthakathaka bubuhlungu ngenxa ye-hormone yeprolactin equlethwe egazini, ejongene nokukwazi ukuqala iinyembezi kunye nokuvelisa ubisi ngexesha lokuncelisa. Kwamadoda, izinga lalo liphantsi, kodwa inani le-testosterone, elithintela ukuqokelela i-tear fluid, liphezulu.
