Ukuqhawula izilonda

Izitho zoqhekeza ziqokelela izakhiwo ze-anatomical ezivelisa iinyembezi kunye nokuguqula ukugqithiselela kwazo kwisigxina somsi. Ziyilungu lembini. Ukuze benze imisebenzi yabo kunye nokubhekiselele kwiimpawu ze-anatomical zendawo, ezi ziko zidibene ngokwahlukileyo kunye ne-secreting device. Imfihlelo eyimfihlo iqulethe i-enzyme engagcini nje ukunyusa i-cornea yamehlo, kodwa iyakhusela nokuvuvukala. Umlambo oqhaqhaqhazelayo uphazamisa ngokugqithiseleyo phezu komhlaba.

Iingqungquthela ze-Lacrimal ezifihla imfihla yamanzi ene-antibacterial artificial agent njenge lysozyme ifumaneka kwiindawo ezixhamlayo zamathambo angena emlonyeni ongaphandle kweso. Ubude bawo buba malunga no-2 ububanzi, kwaye bafana neelmonds. Iingqungquthela ezilahlayo ziqulethwe ngamacandelo amabini: i-orbital (engenhla) kunye nelinye (esezantsi), eyahlukana yi-tendon ye-muscle, ephakamisa ijwabu leso eliphezulu. Ukongezelela, kukho ezinye iingqungquthela ezingaphezulu. Zihlala zikhona kwi-conjunctiva yesigxina esiphezulu.

Ukuze kuphuculwe kakuhle i- eyeball eye ayifuni ngaphezu kwe-1 ml yezinyembezi ngosuku, kwaye zivelisa izilwanyana ezingaphezulu. Ukuba akukho pathologies, ngoko benza umsebenzi omkhulu wemisebenzi yabo. Iingqungquthela eziphambili ziqala umsebenzi wazo ukuba kukho naziphi na izizathu ezivakalayo ezibangele ukwanda. Oku kwenzeka xa zibonakaliswe kwizinto ezahlukeneyo ezivuthayo, umzimba ongaphandle ungena kwi-conjunctiva okanye i-cornea, intlungu enzima, ukukhanya okuphazamisayo okugqithisileyo, ubuninzi beemvakalelo.

Izindlela zeLacrimal ziyi-anatomiki eziyinkimbinkimbi, ezinamalungu amaninzi. Ngaloo nto ikhefu elikhuphayo lihamba kwisikhwama sokudibanisa kwaye iphendulelwa kwisigxina samanzi. Impilo yabo incike kwimpilo yeso sakhiwo esibalulekileyo njengamehlo.

Amaconsi aseLacrimal kwisixa seengxube ezili-12 zikhona kwi-gland nganye kwaye kukuthi imfihlelo emigodini ekhutsheni yekhusi eliphezulu lifaka isikhwama sokudibanisa. Kwiphepha langaphakathi lamaphephephe angaphezulu nezantsi azincinci ezinama-tubercles aneemingxuma, ezibizwa ngokuba ngamaphuzu enkqantosi. Ubuninzi bemfihlo ehlanganiselwe echibini elilahlayo lwenziwa ngabo ngokusebenzisa iindawo zokukhawula, ezibizwa ngokuba yi-tubules. Emva koko kungena uhlobo lomqokeleli - isangxozi yentlungu, aze afike emgodini wamanzi, apho uphupha khona, uhlambe umoya.

Ukugqithiswa komsebenzi kumalungu achasayo kungabangela ezininzi izinto, kubandakanywa ukuvuvukala kweengqungquthela ezilahlayo. Kule meko, i-tear fluid ingaveliswa njengento encinci, kwaye ininzi. Iziganeko eziphambili zezifo ezigulisa i-gland zi: ukukrakra, ukuvakalelwa kwamehlo, ukuvuvukala kwejwabu leso. Kwiinkqubo ezivuthayo, izigulane zivakalelwa, kwaye azikho kwizifo ezingapheliyo.

Iingqungquthela ze-Lacrimal zikhula ngokufihlakeleyo. Oku kuyinyani ngokukodwa kubasetyhini ngexesha lokutshintsha kwe-hormonal. Kukho ukwehla kwenani lezinyembezi kunye ne-Sjögren's syndrome - izifo ze-rhumum nezizathu ezicacileyo ezicacileyo.

Ngokwemvelo, xa ekhala, inani lemfihlo yecala landa kakhulu. Iimeko ezifanayo zenzeka ngengozi yamehlo, ukutshiswa, imizimba yangaphandle, ukucaphuka, umzekelo, xa uhlamba i-anyanisi, njl njl. Ngaloo ndlela umzimba uphendula kwaye ukhusele iso. Ukuvuvukala kweengqungqungquthela eziqhekezayo kubakho rhoqo ngokuphuhliswa kwezifo ezithathelwanayo ezifana nefuthe, imiphunga, umkhuhlane omfusa. Ukuba ukuvuvukala kweentlanzi ezilahlayo kungenabuhlungu kwaye kuhlala ixesha elide, kunokwenzeka ukukrokra ukuba khona kwezifo ezingapheliyo njengesifo sofuba, izifo zesifo se-circulatory, syphilis kunye nabanye.
