Kidney umsebenzi: yabasebenzi imperceptible

Asazi ngokupheleleyo yonke imisebenzi onke amalungu. Izintso azikho kwakhona elula njengoko kubonakala. Nangona umsebenzi esisiseko kwizintso ezaziwayo. Abanye babo bazi nokuba abantu kude amayeza, kunye nabanye abafundi bafumana kuphela - oogqirha elizayo, zebhayoloji kunye oogqirha bezilwanyana. Ubume kunye umsebenzi kwizintso kufundwe iinkcukacha kwi namasebe ngamasebe. Siya kugxininisa ikakhulu kwimisebenzi.

Hayi msebenzi ezaziwayo-kakuhle izintso kukugcina iasidi rhoqo eqhelekileyo egazini. Kakade ke, umzimba onoxanduva inkqubo olunzima akukho namnye kuphela zezintso. Kwakhona yinxalenye yomsebenzi iwela ukukhanya. Recent "Veda" ekuzisweni kweenkonzo carbon igazi dioxide. Kodwa sezintso reabsorb yesoda evela umchamo cell ion ze-hydrogen kulo umchamo, ngoko ukunciphisa acid egazini.

Kwakhona, hayi yonke imihla siva malunga umsebenzi kwezintso, ummiselo plasma osmolality. Ngokuzolileyo, ebumnyameni benza umsebenzi kakhulu ukugcina isixa electrolytes egazini yesiqhelo. "Umphathi ngoko nangoko" kule okukhethekile kwi izintso - le ngxenye. Yena uyakwazi ukubona ukwanda electrolytes egazini kwaye unikeze uphawu ukuba ingqondo yebhinqa. Ngenxa betekisi hormone antidiuretic, nto leyo ebangela izintso ukwenza umchamo kanzulu xaxa, yivusa amaninzi yamanzi yokuchama. Ngoko ke, lo electrolytes eboniswe, yaye amanzi ngakumbi. Ngenxa yoko, umlinganiselo enyibilikayo kunye namanzi - nesinyibilikisi kwakhona uba eqhelekileyo. hormone Antidiuretic iyakwazi ukwenza ezinye iinxalenye nephron akubonakali ngakumbi amanzi kwaye babuyela kokuba lihluziwe igazi.

Enye into ebalulekileyo umsebenzi ummiselo igazi yi xi izintso. Ewe, benza oku nokuthi. ummiselo Long-term kwezalathisi uxinzelelo - izintso zoshishino. Lo msebenzi ebalulekileyo izintso emzimbeni womntu isandula unikwe ingqalelo enkulu cardiologists kwakunye nesifo sentliziyo - i "umbulali 'esikhulu abantu abaselula kakhulu. Ukubuyela nowolawulo sezintso. Kuqeqesho iqaphelwa le Yindibanisela renin, nto leyo echaphazela molecule njani sodium chloride equlethwe egazini. Le nkqubo ibandakanya iihomoni ezifana angiotensin kunye aldosterone, nesigqibo seengcinga amanyathelo yabo inzima kakhulu. Kodwa ekugqibeleni ilawulwa yi umthamo plasma yegazi, yaye oku kuchaphazela uxinzelelo lwegazi. Kungenxa yoko le nto "core" ukusela womchamo, nangona kunjalo, ukuba kube amachiza potassium-zingawucongi xesha elimisiweyo, ngokuba womchamo abadli ukwahlula phakathi electrolytes, kwaye ngaphandle potassium ngokwaneleyo intliziyo embi.

Kwakhona osemqoka umdla kakhulu ke Yindibanisela erythropoietin hormone. Ingakumbi abanomdla kule hormone, abadlali. Inyaniso kukuba ngenxa kwale hormone kwandisa isixa abathwali ioksijini - erythrocytes gemoglobinsoderzhaschih. Ukuba kidney ayikho umoya ngokwaneleyo - aqala ukuvuselela imveliso iiseli ezibomvu. Ngoko ke, ngalo lonke ixesha aninabo ioksijini ngokwaneleyo kuqeqesho, izintso zakho aqale nokulungelelanisa erythropoietin, yaye emva kwethutyana kuza kukho ifuthe loqeqesho - ukwandisa inani abathwali ioksijini.

Kwaye igqiba uhlolo ngayo umsebenzi imveliso yenkunkuma, enyanisweni, lo msebenzi ubalulekileyo nezintso. Kufuneka protein ubomi, kodwa imveliso yokutya emzimbeni wayo - ubuthi zinamandla. Ngokupheleleyo ukurhoxisa amathumbu zabo, kodwa iqashiso buyaqhubeka share zezintso. Zona - abasebenzi ngobunyulu, abasebenzi yenkuthalo, ezenza indawo yethu eqhelekileyo zangaphakathi ekusebenzeni kakuhle. Yeyona ukuphunyezwa kwalo msebenzi kuxhomekeke imithetho yamacebo nephron - unit functional amalungu angaphakathi ya ntumbuluko. Inkqubo igazi nokukhululwa "ubunyhukunyhuku" Isigaba-mbini, kuqala lihluzwe phantse zonke ngoko wabuyela emva egazini. Kwaye kwinqanaba ngalinye kukho iindlela ezinzima yemimiselo.

iimvavanyo umchamo rhoqo - Amanyathelo ubuncinane ukuba singathatha ukuya ukufumanisa imeko nezintso. Akukho mfuneko yokuba ngoyaba impilo ezi abasebenzi abatsha.
