Apho izinto eziyingozi endibafuduse ngegazi? Zikhusela ijwabu yomzimba ulwelo

imithambo yegazi inkqubo yezothutho komzimba. Mzuzwana ngamnye, athwala ezahlukeneyo iikhompawundi, ezinye zazo ayityhefu. Apho izinto eziyingozi endibafuduse ngalo igazi, yaye yintoni iinkqubo kwenzeka nabo emzimbeni?

Zikhusela igazi

zithako kunye amagciwane Various esiza okusingqongileyo yangaphakathi ngokusebenzisa iinkqubo bokuphefumla yokucola ukutya, nto leyo kwi egazini. Abaninzi kubo kunokubangela umonakalo kwaye zibangela izifo ezinobungozi.

Apho entrained igazi kwezinto eziyingozi? Bona senze isenzo of leukocytes. Ezi seli zokuzikhusela okutsala zifunxe zonke iiprothini zasemzini, iintsholongwane kunye ezincane. Le nkqubo ibizwa ngokuba phagocytosis, okanye ukugaywa intracellular. Ngokwenza njalo, iiseli ezimhlophe zegazi kufa kunye abatsha eqalisiweyo kwiindawo nkovu kunye thymus.

Apho izinto eziyingozi endibafuduse ngegazi?

Kunye ukutya umoya ngaphakathi emzimbeni kwaye iintlobo ityhefu. Apho izinto eziyingozi endibafuduse ngegazi? Kuqala kwinto zonke, ukuba sidlule ebizwa ngokuba yi-amalungu umqobo. Cinga indlela amanyathelo yabo umzekelo esibindini.

Lelona nobubovu inkulu ukudla, yona efumana igazi yegazi esiswini kunye amathumbu. Apha luhluzwa kulo iikhompawundi kuluncedo nobumdaka namandla. Ekunye bile, ukuba imveliso ngaphandle. Isibindi kwakhona lwenzeka intshabalalo kutshatyalaliswa erythrocytes phagocytic. Kukhuthaza izinto ezinobungozi kunye engafunwayo kwenzeka xa amalungu zokugaya, yokuphefumla, wokuchama nolusu. Iimveliso exchange eziphambili ziquka carbon dioxide, urea, iityuwa zesinyithi enzima.

Umsebenzi lesondlo igazi

Ngoku makhe sibone, endibafuduse apho kude ngegazi izondlo kutshatyalaliswa. Iiproteni, lipids kunye wekhabohayidreyiti biopolymers. Oku kuthetha ukuba Ziqulethe uluhlu Inani leeyunithi abaphinda. Xa wokugaya iiproteni ukubola zibe asidi acid, polysaccharides - in carbohydrate, kunye namafutha - glycerin kwaye carboxylic asidi ephakamileyo.

Ngenxa yoko isixa esithile wamandla iyekelela esetyenziswa ukuphumeza eziphilayo iinkqubo zobomi. Kutheni ukutshatyalaliswa biopolymers? Yonke le nto kukuba molecule awo makhulu kakhulu. Ngoko ke, abanako ukungena ukusuka phecana sokugaya egazini. Le monomers kwakhona yenza oku lula. Ekubeni igazi ngoku kondliwa ngawo iiseli kunye namacandelo apho kwakhona kukho "indibano 'yawo ukwakha izinto ezintsonkothileyo eziphilayo.

Ukuphunyezwa exchange igesi

Gas unaniso lingunqontsontso kwimisebenzi yomzimba eqhelekileyo. ngokuma, oxygen engena emiphungeni, nto leyo eziqulathe inani elikhulu amaqamza amancinci - le alveoli. Indima kwezi zakhiwo ezincinane yeyabahlali. Kungenxa exchange igesi alveoli kwenzeka phakathi kweenkqubo bokuphefumla kwegazi.

Umsebenzi wabo isoloko kwenziwa kunye. Mpilo, igcwala kwezinto eziphilayo, kubangele ukusekwa carbon dioxide. Le nto yenza elibona ezingazinzanga ne mpilo. zenziwa phi ikharbon igazi dioxide kunye nomphunga wamanzi? Kakade ke, emva imiphunga, koko uwukhuphe, zithulwe emzimbeni.

Ngoko ke, kweli nqaku siza kuxoxa, leyo basusa igazi kwezinto eziyingozi. Emzimbeni, ziya ebizwa ngokuba yi-imigca eziliqela zokhuselo. Ezi igazi kunye nkovu, zesisu phecana, umhlehlo, nezintso, ulusu kunye nemiphunga. Icandelo bangabi ezingcolisayo ezikuwo, kwaye ezinye uyaphuma imizimba ukhetho. Ngokusebenzisa le nkqubo ibizwa igcinwa ngaphakathi rhoqo kunye zikhusela igazi luyenziwa.
