Kuj nug, dab tsi yog qhov ib puag ncig ntawm lub cev?
ib puag ncig sab hauv Cov xwm txheej uas yeej nyob hauv lub cev ntawm ib qho kab mob , tshwj xeeb tshaj yog nrog rau kev muaj pes tsawg leeg ntawm cov ntaub so ntswg. Tsiaj txhu ntxiv tuaj yeem tswj lawv lub cev kua los ntawm kev ua haujlwm ntawm cov tshuaj hormones thiab lub paj hlwb. Saib homeostasis.
Tom qab ntawd, lo lus nug yog, kev saib xyuas homeostasis yog dab tsi? homeostasis . tus kev saib xyuas los ntawm cov kab mob ntawm ib puag ncig sab hauv; Ib qho piv txwv yog kev tswj hwm cov piam thaj hauv cov ntshav los ntawm insulin. Cov txheej txheem muaj xws li tus kheej-kho mechanisms uas lub kev saib xyuas ntawm ib theem tshwj xeeb yog pib los ntawm cov khoom kom tswj tau.
Tsis tas li lo lus nug yog, cov kab mob ua li cas tswj tau qhov chaw nyob ruaj khov?
Tej yam muaj sia Ua kom ruaj khov hauv cov xwm txheej Thaum koj yog sov dhau, koj tawm hws kom tso cua sov. Thaum twg muaj sia nyob kab mob tau muab pov tseg los ntawm kev sib npaug, nws lub cev lossis cov hlwb pab nws rov qab los. Kev tuav pov hwm qhov sib npaug hauv lub cev lossis cov hlwb ntawm kab mob hu ua homeostasis.
Vim li cas nws tseem ceeb rau cov khoom muaj sia kom muaj kev ruaj khov nyob hauv ib puag ncig?
Kev tuav pov hwm ib ib puag ncig sab hauv los ntawm kev muab cov cell nrog dab tsi lawv yuav tsum tau muaj sia nyob (oxygen, as-ham, thiab tshem tawm cov khib nyiab) yog qhov tsim nyog rau qhov zoo. ua ntawm ob leeg cell thiab tag nrho lub cev.
