Homeostasis - ukulondoloza ukulinganisela yemvelo

Homeostasis - ikhono kohlelo organic ulondoloze ukulinganisela kuqhathaniswa njalo othakazelisayo imvelo yangaphakathi. Leli gama livela ngesiGreki. It has a isakhiwo eziyinkimbinkimbi ezakhiwe amagama amabili - homoios (efanayo) kanye stasis (state). Izinqubo ukuzithiba ukuqinisekisa ukuqinisela we bokuphila, ngokuthi homeostatic. Kuye Sakhiwo sangekhatsi uhlelo evulekile kanye nokuxhumana yayo nge imvelo, fixed isekela izindlela esinjalo kungase kudingeke izakhiwo ezahlukene:

- ukuntengantenga okunemibandela kohlelo kuqinisekisa nezimo esiphezulu kule mibandela edingekayo;

- Ukulwela ukulinganisela ukulondolozwa lisiza ekulondolozeni ukulinganisela eyisihlobo isakhiwo kanye nenhlangano obusebenzayo kohlelo;

- umphumela ezingalindelekile ivumela methodically ukufeza imiphumela emisha anomthelela eragela yezici enemitheshwana.

Njengoba homeostasis - isimo esekelwe impambano nge imvelo, izinhlelo ezinjalo kungaba ngokuvamile yayiba nezinhlobo ezimbili impendulo: emihle nemibi. Negative impendulo lwesistimu kubonakala ekusabeleni eshintsha izinguquko nenshisekelo kolunye uhlangothi. Impendulo lisiza ekulondolozeni isimo unomphela uhlelo, ngokusiza silinganise ukuhambisana. Isibonelo uxhumano ezifana ongakhonza thermoregulation kubantu. Homeostasis - inqubo eyinkimbinkimbi nokuxhumana phakathi zonke izingxenye ngamunye ohlelweni ngabanye. umzimba lokushisa thermoreceptors Ukwandiswa noma kwehle ngxenye futhi isikhumba ngokushesha ukubhalisa shintsho. Lokhu isignali idluliselwa ku ubuchopho, elibangela impendulo ephambene umzimba - ukwehlisa noma ophakamisa izinga lokushisa.

okubuyayo is kuveziwe embikweni okhuthaza ukwanda kwe-variable. elihlangana okunjalo kubangela destabilization umphumela, ngakho ungakuvumeli ukuba inqubo. Kuyinto ingasaphathwa ezivamile ukusebenza izinhlelo organic, kodwa futhi unalo ukubaluleka kwayo. Homeostasis - a uhlelo ezidinga inhlanganisela yakho kokubili izinhlobo impendulo. Ngokwesibonelo, okulinganisela ezingaba kagesi ezinzwa yisizukulwane nakakhulu isenzo ezingaba khona. Ngakho, i-okubuyayo kuyadingeka ukuze ushintsho esimweni entsha homeostasis. Izinguquko ezinjalo, ngakho abizwa ngokuthi metastable. Izibonelo ushintsho olunjalo kungase kube ukwenyuka umsoco imifula yamanzi ecacile, okuholela ingaphazamisi kwesigubhu ukuphendula kanye ulwelwe overgrowth isiteshi salo.

Homeostasis ecosystem - bemvelo othakazelisayo ukuzinza kwemvelo ngokusebenzisa ukuvuselelwa njalo izakhi zalo eziyisisekelo. Umqondo yakhoibrium ngokwemvelo ayekade akhiwa sezitshalo American futhi semvelo Frederikom Klementsom. Ngaphezu kwalokho kokusele semvelo ukuhlukanisa begazi, homeostasis yeselula nokulinganisela emzimbeni womuntu. Leli khono kumelwe kuqondwe njengokusho isici jikelele izinqubo eziningi njalo uxhumana nomunye.
