Ukuphefumula inqubo lapho izinto eziphilayo zithola khona i-oxygen ukuze ziphile. Kungaba yi-pulmonary, branchial, tracheal noma i-cutaneous. Ezinye izilwane zinezinhlobo ezingaphezu kweyodwa zokuphefumula ngasikhathi sinye.

I- ukuphefumula kwamaphaphu Kwenziwa yizilwane ezincelisayo (kufaka phakathi abantu), izinyoni, nezinambuzane eziningi nezilwane eziphila ezweni. Ngokwesibonelo: unogwaja, isikhova, isibankwa, isele.

Ziyizinto eziphilayo ze-aerobic, amaseli azo adinga umoya-mpilo ukuze aphile. Ngesikhathi sokuphefumula kwamaphaphu, amaphaphu (izitho eziphakathi kwalolu hlobo lokuphefumula) ashintshanisa amagesi phakathi kwesilwane nendawo yemvelo. Umzimba uphefumulela emakhaleni noma emlonyeni umoya-mpilo odingwa amaseli ukuze usebenze futhi uphele isikhathi sesikhutha esiwalahlayo.

Ukuphefumula kwamaphaphu ezilwaneni ezincelisayo

Ukuphefumula kwamaphaphu mammalian, umoya-mpilo ungena emzimbeni wesilwane ngomlomo noma ngamakhala. Idlula kwi-pharynx, larynx, trachea futhi ekugcineni ifinyelele emaphashini nge-bronchi. Ngaphakathi kwamaphaphu, igatsha le-bronchi liphuma futhi lenze ama-bronchioles agcina ku-alveoli, amasaka amancane lapho kushintshaniswa khona i-oxygen ne-carbon dioxide. Ngesikhathi sokuphefumula, amaphaphu ayaqina futhi ayanwebeka.

I-oksijeni isetshenziswa kumaseli egazi (amangqamuzana abomvu egazi) asatshalaliswa emzimbeni wonke ngohlelo lokujikeleza kwegazi, olukhishwa ngendlela efanayo eguquguqukayo yesikhutha.

Ukuphefumula kwamaphaphu kuma-amphibians

Ama-Amphibian angama-vertebrate angahlala ezindaweni zombili zasemanzini nasemhlabeni, ngenxa yalesi sizathu, izinhlobo eziningi ziphefumula ngesikhumba sazo lapho zisemanzini, nangamaphaphu azo lapho zisemhlabeni.

Ama-Amphibians enza i-metamorphosis kukho konke ukukhula kwawo. Esikhathini sayo sokuphefumula, ukuphefumula yi-gill. Amaphaphu nezitho zezilwane eziphila emanzini nasemanzini ziyakhula lapho zifinyelela esigabeni esincane.

Ama-Amphibians athola i-oxygen ngamakhala nangomlomo. Banamaphaphu amabili ane-faveoli.

Ukuphefumula kwamaphaphu ezihuquzelayo

Ukuphefumula kwezinambuzane eziningi zomhlaba kufana nokwesilwane esincelisayo. Zimunca umoya ngamakhala noma ngomlomo obese udlula kwi-pharynx, larynx, trachea ukuze ufinyelele emaphashini ahlukaniswe nge-septa.

Izilwane ezinwabuzelayo eziningi zinamaphaphu amabili. Ezinye izinhlobo zezinto eziphilayo njengezinyoka zineyodwa kuphela.

Izilwane ezihuquzelayo zasemanzini eziphefumula ngamaphaphu zithola umoya-mpilo ebusweni bese uzigcina emaphashini ukuze zisetshenziswe lapho zingaphansi kwamanzi.

Ukuphefumula kwamaphaphu ezinyonini

Izinhlobo eziningi zezinyoni zinamaphaphu amabili amancane lapho kwenzeka khona ukushintshaniswa kwegesi. Izinyoni zidinga inani elikhulu lomoya-mpilo elizisebenzisayo ukundiza. Ngokungafani namaphaphu ezilwane ezincelisayo, amaphaphu ezinyoni awanayo i-alveoli kodwa i-parabronchi, ebhekele ukushintshaniswa kwegesi.

Umoya ungena emzimbeni ngomlomo noma ngekhala emgqeni womoya, bese udlulisela ingxenye uye emaphashini bese ingxenye uyisa ezikhwameni zomoya. Amasaka omoya ayizakhiwo ezinezinyoni, zidluliselwa emaphashini futhi zigcina nomoya. Lokhu kuvumela ukuthi banciphise isisindo sabo ukuze banikeze amandla xaxa ngesikhathi sendiza. Amasaka omoya agcina amaphaphu engena umoya njalo.

Izibonelo zezilwane ezincelisayo eziphefumula amaphaphu

Izibonelo zama-amphibians aphefumula amaphaphu kanye nezilwane ezihuquzelayo
