Imiba yempilo Recent: yintoni imisebenzi yenziwa yi nezintso, kwaye ukuba kuyimfuneko ukuba ukuzigcina zikwimeko entle?

Yiyiphi imisebenzi wezintso kwaye oko abamele? Lo mbuzo umdla kakhulu. Sonke siyazi ukuba uhlobo igunya, kodwa akubonakali uninzi liya kuba nako ukunika inkcazelo ngqo. Kaloku, kuyimfuneko ukulungisa kwaye uxelele bonke zisisiseko kwaye ebalulekileyo kulo mzimba.

inkcazo emfutshane

Ukuthetha ngezinto imisebenzi yenziwa yi nezintso, into yokuqala kukuba ukunika inkcazo epheleleyo kule kota. Kuya kuba echanekileyo. Izintso zidityaniswe ilungu imbotyi ezimile elawula homeostasis eekhemikhali emzimbeni womntu. Kwaye kwenzeka ntoni xa ngeendleko umsebenzi umchamo Ukwakheka. Ngenxa yesizathu esifanayo, umzimba iyinxalenye yenkqubo womchamo. Le ise kwisikhewu retroperitoneal (ukuba ngqo ngakumbi, kummandla empontshwa, macala omabini yomqolo). Ekugqibeleni, izintso - yeziko, kudlala indima enkulu ebalulekileyo kwinkqubo yokuqulunqa ngumchamo. Yaziwa, ulwelo, equlethe izinto ukuba ikakhulukazi inkunkuma.

Ukwenziwa ulwelo uric

into Ukuxoxa imisebenzi yenziwa yi-kidney, oko kuyimfuneko kuqala ukuza kukuxelela. Okoko kwasekwa umchamo - engundoqo "umsebenzi" lomzimba. Ekuqaleni, amanzi kunye nezinye ulwelo kuhluzeka lokucoca glomerular umaleko emithathu (i-corpuscle kwezintso, uhlobo "ngesihlungulo"). Candani phakathi iiproteni ikakhulu plasma. Kwandula ke tubules uya umchamo ephambili. Kwezi, ulwelo kufuneka ukuba zifunxwe ngumzimba, kwakunye iintlobo zezondlo. Inqanaba lokugqibela ubizwa ngokuba "secretion tubular." Ngethuba lale nkqubo, kudlule zonke izinto umzimba okungeyomfuneko ukusuka igazi umchamo zasesekondari, ngoko leyo isuke kwi lwesinye. Vele ubeke, yonke into kunokuba luncedo ukuba sihlale egazini kwaye isasazwe ngokusebenzisa iimpahla. A izinto eyingozi enokubangela umonakalo emzimbeni okanye ivule sifo, ukugula, virus - uzayo uhlobo ngumchamo. Ngoko kucacile ukuba kutheni le kwizintso zidla ngokuba lokucoca ulwelo yethu.

Yintoni umdla ukwazi

Yiyiphi imisebenzi lwenziwa yi-kidney ukongeza kukhuthaza iimveliso ekupheleni ukutya? Enyanisweni, abaninzi. Kukho ezintlanu - secretory, homeostatic, metabolic, yonyango, yaye uyasikhusela. Loo nto iye yachazwa ezingasentla lokuqala. Yaye oko bekuya kuba kunqweneleka ukuba bajolise ingqalelo.

Okubangel 'umdla kukuba, iiyure ezingama-24 ngokusebenzisa izintso udlula malunga 1500 (!) Iilitha igazi! Yaye bambalwa siyazi ukuba ephuma nto malunga 180 iilitha nomchamo. Figure kubonakala amazing. Kodwa ngokwenene - 180 iilitha umchamo iilitha 1500 igazi. Nangona kunjalo, olu kuphela isanda. Ngoko kukho ukufunxeka kwamanzi ngumzimba. Lilonke ukuba Inqanaba lokugqibela, ezona neelitha ezimbini ulwelo umchamo, nokuba umntu okhupha. Hi ndlela leyi, le ukwakhiwa ilulwelo oku kulandelayo: 95% amanzi kunye ne-5% eziqinileyo ezomileyo. Kodwa oku, Kakade ke, umntu eqhelekileyo. Umzekelo, abantu abaphethwe butywala, umchamo iqulethe iproteni (utywala kunye neemveliso ezilungiswa). Oku kungenxa yokuba ukuphazamiseka imisebenzi eqhelekileyo nezintso. Xa iindlamanzi ezi imizimba khangela eyoyikekayo, uze ufumanise ukuba ke komzimba kunokwenzeka. Izintso Undintshwenyisile, mnyama, namabala bulubhelu kunye ukudumba ezinkulu (ayegqunyelelwe kwizicwili). imizimba enjalo angabi nako ukusebenza ngokuqhelekileyo. Ngenxa yoko - zonke izinto eziyityhefu kuhlala egazini. Kwaye ngokufanelekileyo, vuka kunye nokuphuhlisa kwezifo, abanobubi esisisiphumo zokufa.

umsebenzi Homeostatic and metabolic

Kwakhona iinkqubo ebaluleke kakhulu. Xa lalizixubusha uhlobo lomsebenzi lwenziwa yi zabantu kidney, asingekhe silibale malunga homeostatic kunye metabolic. Lo mzimba lilawula ngokutshintshiselana igazi, ezizezi ukurhoxiswa ion abangaphezu kwemfuneko kunye protons, nebhiKharbonati igazi. Ukongeza, kube nefuthe kwityala fluid emzimbeni womntu ngokulawula umxholo ion.

Ke umzimba carbohydrate, lipids, iiprotheni, cleavage le peptides, acid - oko kukuthi yintoni umsebenzi lwenziwa yi nezintso! Oku kulo mzimba a luncedo ivithamin D iguqulelwa ngohlobo D3, apho kuyimfuneko kangaka abantu ukugcina inkqubo ziphile. Nezintso othatha inxaxheba kwinkqubo protein yokuqaphela. Ngoko ayikho kuphela ukuyilwa umchamo lo "umsebenzi" lomzimba.

Synthesis nokukhuselwa

Yiyo le into yokugqibela ekufuneka zikhankanyiwe, ukuthetha ngezinto uhlobo lomsebenzi lwenziwa yi izintso emzimbeni. Lo mzimba ukongeza kungasentla ayabandakanyeka kule Yindibanisela prostaglandins, renin, erythropoietin, kunye calcitriol. Xa sithetha ngolwimi olulula, oko kunceda ukwakha iintlobo hormone enzayim kubalulekile kuthi. Le arhente ukulawula uxinzelelo kwi imithambo lize igazi wahlala elungelelene nokulawula imali ikhalsiyam emzimbeni.

Ekugqibeleni, ukukhuselwa. Nantsi into umsebenzi lwenziwa yi izintso ebantwini. Nge neutralization yabo kwenzeka nge zizinto ezahlukeneyo yalapha (okanye embi nje) ebonakala umzimba. Kuyinto utywala, inicotine, iziyobisi kunye neziyobisi esinamandla. Kunqweneleka ukuba kuncitshiswe consumable izinto. Ngokupheleleyo, Kakade ke, kuya kusebenza: Ukuba umntu akatshayi aze angadli, amayeza uthabatha ngamanye amaxesha, kwaye kananjalo oko kudala ngumthwalo nezintso. Ngoko ke kuyimfuneko ukuba abakhusele. Ukuze wenze oku, usele amanzi acocekileyo (oko ezimbiwa kunokwenzeka), iti eluhlaza, Mora cowberry usele cranberry zobusi lemon, parsley umhluzi. Kulwelo kufuneka ngokubanzi iilitha ezi-2 ngemini. Ukuba uyalandela eli cebiso elula, uya kuxhasa izintso zikwimeko entle kwaye kuthintela ukuyilwa ngamatye. Ukanti kunqweneleka ukuba ayeke ikofu, utywala kunye soda. Ubhubhisa iiseli zezintso kuphela.
