Isikhumba seegusha sineempawu ezifana nokungena komoya, ukugcina ubushushu kunye nokufunxa ukufuma.
Ifiber yegusha yifayibha “yokuphefumla” eyodwa, kwaye inceda ukulawula ubushushu bomzimba.Umaleko wokuhamba komoya wenziwa phakathi kwemicu ephantsi kwesikhumba, ebonelela ngobushushu obufanelekileyo obungaguqukiyo bomzimba womntu kwaye yenza abantu bazive behlaziyekile, bekhululekile kwaye bethambile. Ubushushu bangaphandle buphezulu kakhulu okanye buphantsi kakhulu, umahluko wobushushu bomphezulu wegusha awuyi kuba nawo kakhulu. utshintsho olukhulu, ifayibha yegusha yi-conductor engalunganga yobushushu, ifayibha iqulethe umoya omninzi, yenza umaleko ogqwesileyo wokugquma.
Iintsinga zofele lwegusha ziyamelana namanzi ngokwendalo, kodwa zifunxa ama-35% obunzima bazo kumphunga wamanzi zize ziwukhuphele emoyeni ngesantya esithile, nto leyo idala imicrocirculation yomoya phakathi kwesikhumba kunye nempahla. ifumile, ngaloo ndlela ikunika imvakalelo eyomileyo neyonwabisayo.Oku kuluncedo kakhulu ekunyangeni isifo samathambo kunye nesifo samathambo.
Isikhumba seegusha sityebileyo, sithambile kwaye sithambile, esinokuthi sisasaze uxinzelelo lwesikhumba somntu, ngakumbi indawo yokunyusa amathambo.Xa ubunzima bomzimba bujikeleza, kunempembelelo ethile yokuphulula ukuvuselela i-capillaries, enenzuzo ekuphuculeni ukujikeleza kwegazi kwesikhumba.Inokuphelisa ukukhathala kwemisipha kunye neentlungu ezidibeneyo ukuya kwinqanaba elithile.Umsantsa wefiber woboya unokufunxa kwaye usasaze ukubila kunye ne-oyile ekhutshelwa lusu lomntu, nto leyo enceda kwimetabolism yolusu kunye nokwandisa amandla okuxhathisa izifo zolusu.
Iimbobo zesikhumba zincinci, zisasazwa ngokulinganayo, zithambile, ziphefumula kwaye zifudumala, umbala omhle kwaye uziva uthambile kwaye ugudile.Kwaye ngoku ngokuxhomekeke kwiimfuno zobomi ezingaphezulu nangaphezulu, izihlangu zesikhumba zeegusha zenzelwe izitayela ezahlukeneyo, ukuhambelana neendlela ezahlukeneyo zeempahla. , unokuya nasiphi na isiganeko, imfashini kakhulu, ngoku abantu abaninzi ngakumbi bathanda olu hlobo lwezihlangu, kuba luyimfashini kwaye lusebenza.
