Izinhlanzi, kanye nezilwane zasemhlabeni noma izilwane ezincelisayo zasemanzini, zidinga ukuthatha i-oxygen ukuze ziphile, lokhu kungomunye wemisebenzi yazo ebalulekile. Kodwa-ke, izinhlanzi azitholi umoya-mpilo emoyeni, ziyakwazi ukuthatha i-oxygen encibilikiswe emanzini ngesitho esibizwa nge-brachia.
Ufuna ukwazi okwengeziwe nge- izinhlanzi ziphefumula kanjani? Kule ndatshana kaPeritoAnimal sizochaza ukuthi uhlelo lokuphefumula lwe-teleost fish lunjani nokuthi ukuphefumula kwabo kusebenza kanjani. Qhubeka ufunde!
Inhlanzi iphefumula kanjani umoya-mpilo okhona emanzini
Ngo- brachia of teleost fish, okuyizinhlanzi eziningi ngaphandle koshaka, imisebe, izibani kanye ne-hagfish, kuyatholakala. ezinhlangothini zombili zekhanda. Ungabona umgodi opercular, oyingxenye "yobuso bezinhlanzi" ovula ngaphandle futhi obizwa nge-operculum. Ngaphakathi komgodi ngamunye opercular kukhona i-brachia.
I-brachia ixhaswa ngokwesine ngabane imengamo brachial. Kusuka entengweni ngayinye ye-brachial, kunamaqembu amabili emicu ebizwa ngokuthi imicu ye-brachial enesimo se- "V" maqondana ne-arch. Intambo ngayinye igqagqana nentambo engomakhelwane, yakha i-tangle. Bona laba imicu brachial banezinhlelo zabo ezibizwa ngama-secondary lamellae. Lapha kwenzeka ukushintshaniswa kwegesi, izinhlanzi zithatha umoya-mpilo futhi zikhiphe isikhutha.
Inhlanzi ithatha amanzi olwandle ngomlomo futhi, ngenqubo eyinkimbinkimbi, ikhipha amanzi nge-operculum, ngaphambili eyayidlula ilamellae, lapho ikhona thatha umoya-mpilo.
izinhlanzi zokuphefumula
O izinhlanzi zokuphefumula ithola igama le-oro-opercular pump. Iphampu yokuqala, i-buccal, inengcindezi eyakhayo, ithumela amanzi emgodini opercular futhi, nawo lo mbobo, ngokusebenzisa ingcindezi engemihle, umunca amanzi emgodini womlomo. Ngamafuphi, umgodi womlomo udonsela amanzi emgodini opercular futhi lokhu kuyamunca.
Ngesikhathi sokuphefumula, inhlanzi ivula umlomo wayo kanye nesifunda lapho ulimi lwehliswa khona, okwenza amanzi amaningi angene ngoba ingcindezi iyancipha futhi amanzi olwandle angena emlonyeni ngokuthanda i-gradient. Ngemuva kwalokho, ivala umlomo inyuse ingcindezi futhi ibangele ukuthi amanzi adlule emgodini opercular, lapho ingcindezi izobe iphansi.
Ngemuva kwalokho, izinkontileka zomgodi opercular, ziphoqa amanzi ukuthi adlule kwi-brachia lapho i- ukushintshaniswa kwegesi futhi ishiye ngokungatheni ngokusebenzisa i-operculum. Lapho iphinda ivula umlomo wayo, inhlanzi ikhiqiza ukubuya okuthile kwamanzi.
Funda ukuthi izinhlanzi zizala kanjani kulesi sihloko se-PeritoAnimal.
Izinhlanzi ziphefumula kanjani, ingabe zinamaphaphu?
Naphezu kokubonakala kuphikisana, ukuziphendukela kwemvelo kuye kwaholela ekuveleni kwezinhlanzi zamaphaphu. Ngaphakathi kwe-phylogeny, bahlukaniswa ekilasini I-Sarcopterygii, ngokuba namaphiko afekethisiwe. Lezi zingubo zamaphaphu kukholakala ukuthi zihlobene nalezo zinhlanzi zokuqala ezaveza izilwane zasemhlabeni. Kunezinhlobo eziyisithupha kuphela zezinhlanzi ezinamaphaphu, futhi sazi kuphela ngesimo sokongiwa kwezinye zazo. Abanye abanalo ngisho negama elijwayelekile.
Ngo- izinhlobo zezinhlanzi ezinamaphaphu yilezi:
- IPiramboia (Lindida ye-epidosiren);
- I-African lungfish (I-Protopterus annectens);
- I-Protopterus amphibius;
- I-Protopterus dolloi;
- I-Australian lungfish.
Yize zikwazi ukuphefumula umoya, lezi zinhlanzi zinamathele kakhulu emanzini, noma ngabe ziyindlala ngenxa yesomiso, zicasha ngaphansi kodaka, zivikele umzimba ngongqimba lwamafinyela ezikwaziyo ukuzikhiqiza. Isikhumba sizwela kakhulu ekuphelelweni amanzi emzimbeni, ngakho-ke ngaphandle kwaleli su ngabe bafa.
Thola izinhlanzi eziphefumula emanzini kulesi sihloko nguPeritoAnimal.
Ukulala kwezinhlanzi: incazelo
Omunye umbuzo oletha ukungabaza okuningi phakathi kwabantu owokuthi izinhlanzi ziyalala yini, ngoba zihlala zivule amehlo. Izinhlanzi zine-nucleus ye-neural enesibopho sokuvumela isilwane ukuba silale, ngakho-ke singasho ukuthi inhlanzi iyakwazi ukulala. Noma kunjalo, akulula ukubona uma inhlanzi ilele ngoba izimpawu azicaci njengokuthi, esiswini esincelisayo. Esinye sezimpawu ezisobala ukuthi inhlanzi ilele ukungasebenzi isikhathi eside. Uma ufuna ukwazi imininingwane eminingi ngokuthi izinhlanzi zilala kanjani futhi nini, hlola le ndatshana yePeritoAnimal.
