Homeostasis - ke ho boloka ho leka-lekana ea tlhaho

Homeostasis - bokhoni ea tsamaiso ea manyolo ho boloka batlang e le kamehla e matla ho leka-lekana ea tikoloho ka hare. lentsoe lena e tsoa ho Segerike. E na le sebopeho rarahaneng thehoa ka mantsoe a mabeli - homoios (tšoanang) le stasis (boemo). The mekgwa boitšoaro ho tiisa hore tiisetso ea fisioloji ea bitsoang homeostatic. Ho itšetlehile ka sebopeho hare ea tsamaiso e bulehileng le sebelisana lona le tikoloho, e tsitsitseng e tshehetsa mekgwa joalo ka 'na na le makgetha a ho fapaneng:

- tlas'a maemo a ho se tsitse ha ea tsamaiso ea etsa bonnete ba ho ikamahanya le maemo palo e kahodimodimo ho maemo a hlokahalang;

- leka bakeng sa ho leka-lekana polokesegong thusa ho boloka ho leka-lekana a lekanyelitsoeng ea sebopeho le mokhatlo o hlophisitsoeng oa mosebetsi ea tsamaiso;

Ka homeostasis - boemong thehiloeng fapanyetsana le tikoloho, tsamaiso e joalo ho ka ba le mefuta e 'meli ea poeletsotlaleho: ntle' me negative. Mpe oona tsamaisong ditshwaelo tsa mofuta e bontšoa ke ikutloa ka tsela eo liphetoho liphetoho aspiration ka lehlakoreng le fapaneng. Feedback thusa hore re lule re le boemong ka ho sa feleng ea tsamaiso ea, ho thusa ho leka-lekanya ho latelwa. Mohlala oa joalo mabapi le ka sebeletsa thermoregulation batho. Homeostasis - e rarahaneng tshebetso ya ho sebelisana pakeng tsa metsoako e tsohle tsa tsamaiso e mong le e mong.

Homeostasis tikoloho - e matla sebopeho sa ho leka-lekana tlholeho ka nchafalo ea kamehla ea likarolo tsa lona tsa motheo.
