Ucwaningo ku-thermo-physiology lukwazile ukunquma ukuthi azikho izigaba ezimbili kuphela (izilwane ezinegazi elibandayo nezilwane ezinegazi elifudumele) lapho imiqondo yomibili ingasetshenziswanga khona.
Kodwa-ke, zombili lezi zihlukaniso zisetshenzisiwe futhi ziyaqhubeka nokusetshenziswa ngokweqile, yingakho incazelo yazo ibaluleke kakhulu.
I-izilwane ezinegazi elifudumele Yilezo ezingakwazi ukugcina izinga lokushisa lomzimba elingaguquguquki kungakhathalekile ukwehluka kwesimo sezulu semvelo. Izilwane eziningi ezincelisayo zigcina ukushisa komzimba kwangaphakathi phakathi kuka-34º no-38º.
Zingaba nokuhlukahluka okuthile ekushiseni komzimba, kepha lokhu kuvame ukuba kuncane. Ngamanye amagama, lezi zilwane kuthiwa zine-homeostasis eshisayo. Izilwane ezinegazi elifudumele zaziwa nangokuthi ama-endotherm.

Izinhlobo ze-thermoregulation
Izilwane ezinegazi elifudumele zinezici ezintathu ezihlukene ze-thermoregulation:
- Endothermy. Ezinye izilwane ezinegazi elifudumele zinekhono lokukhiqiza ukushisa kwangaphakathi emzimbeni wazo. ukubonakaliswa okufanayo kubonakala ngemuva kokuqhaqhazela, ukukhefuzela noma ukushisa amafutha.
- Umama. Lesi simo phambilini besaziwa njengezilwane ezinegazi elifudumele, yize singesinye sezici ezintathu lolu hlobo lwesilwane olungaletha. Kuyisici sokugcina ukushisa komzimba okuqhubekayo futhi kuphakeme kunezinga lokushisa elikhona.
- I-Tachymetabolism. Lezi zilwane zigcina isilinganiso esiphakeme semetabolism ekuphumuleni.Ngamanye amagama, bayizilwane ezigcina ukushisa komzimba ngemuva kokuphumula ngoba, ngale ndlela, zigcina ukushisa komzimba kwazo.
Yize izilwane ezincelisayo nezinyoni eziningi, njengezilwane ezinegazi elifudumele, zibonisa zonke izici ezintathu ze-thermoregulation, ezimweni ezithile kuye kwatholakala ukuthi kungenzeka zingakhombisi zontathu. Ngakho-ke, endabeni yamalulwane noma ezinye izinyoni ezincane, zingaba nezici ezimbili kwezintathu. Kodwa-ke, zisabizwa njengezilwane ezinegazi elifudumele.
Yize leli gama okwamanje lingasasetshenziswa ngokwesayensi kusukela lapho kusetshenziswa izilwane ezi-ectothermic, lesi sigaba sibhekisela kulezo zilwane ezilawula ukushisa komzimba wazo ngokuya ngezinga lokushisa kwemvelo.
Ngokuvamile, izilwane ezinegazi elibandayo zihlala ezindaweni ezishisa kakhulu futhi azibonwa njalo ezindaweni ezibandayo. Noma kunjalo, kungahle kube nokuhlukile.

Izinhlobo ze-thermoregulation
- U-Ectothermy. Zonke izilwane ezinegazi elibandayo zingabhekwa njengezilwane ze-ectothermic ngoba zilawula izinga lokushisa lomzimba wazo maqondana nokushisa kwemvelo.
- Poikilothermia. Ziyizilwane ezilawula izinga lokushisa lomzimba wazo ngokulingana nendawo ezakhelene nayo ngokushesha.
- I-Bradymetabolism. Ziyizilwane ezahlukahluka ijubane lomzimba wazo ukulawula ukushisa komzimba wazo ngokuya ngokudla okukhona kanye nezinga lokushisa elikhona.
Njengezilwane ezinegazi elifudumele, akuzona zonke izilwane ezinegazi elibandayo ezinezici ezintathu zokuthambisa.
Ziyini izilwane ze-ovoviviparous?
Ngemuva kokubeka izilwane ezimbili, enye enegazi elibandayo kanti enye inegazi elifudumele, ngaphansi kokukhanya kwe-infrared, isilwane esinegazi elifudumele sibonakala sikhipha ukukhanya kwaso, okungukuthi, ukushisa kwaso. Ngokuphambene nalokho, isilwane esinegazi elibandayo sihlala simnyama ngombala.
Ngalesi sizathu, izilwane ezinegazi elibandayo zidinga ukuhlala ezindaweni ezifudumele futhi zifudumeze umzimba wazo ngokushiswa yilanga noma ngokusebenzisa ezinye izindlela zangaphandle ukukhuphula izinga lokushisa komzimba.
