Kev sib pauv roj yog xa cov pa oxygen los ntawm lub ntsws mus rau cov hlab ntshav, thiab tshem tawm cov pa roj carbon dioxide los ntawm cov hlab ntshav mus rau lub ntsws. Nws tshwm sim hauv lub ntsws nruab nrab ntawm alveoli thiab lub network ntawm cov hlab ntshav me me hu ua capillaries, uas nyob hauv phab ntsa ntawm alveoli.
Ib yam li ntawd, tib neeg nug, lub npe twg zoo tshaj piav txog txheej txheem kev sib pauv roj?
Cov pa nkag mus rau hauv cov ntshav ntawm qhov chaw ntawm lub plawv, thiab cov pa roj carbon dioxide nthuav mus rau hauv cov ntshav ntawm qhov chaw ntawm alveoli. Cov pa roj carbon dioxide nthuav mus rau hauv cov ntshav ntawm qhov chaw ntawm lub plawv, thiab cov pa nkag mus rau hauv cov ntshav ntawm qhov chaw ntawm cov ntaub so ntswg.
hom kev sib kis yog hloov pauv roj li cas? Kev sib pauv roj tau ua tiav los ntawm kev sib kis. Qhov no yog txheej txheem uas cov khoom txav mus los ntawm ib cheeb tsam uas lawv nyob rau hauv siab rau ib cheeb tsam uas lawv nyob qis dua. Lawv txav mus rau a gradient siab : steeper qhov gradient, qhov nrawm dua ntawm kev nthuav tawm.
Tom qab ntawd, ib tus tuaj yeem nug, vim li cas kev sib pauv roj tseem ceeb?
Kev sib pauv roj yog tseem ceeb vim tias nws muab cov pa oxygen rau cov cell ntawm cov kab mob muaj sia kom lawv tuaj yeem tau txais lub zog los ntawm cov organic molecules.
3 lub hauv paus ntsiab lus ntawm kev sib pauv roj yog dab tsi?
Peb txheej txheem yog qhov tseem ceeb rau kev xa cov pa oxygen los ntawm huab cua sab nraud mus rau cov ntshav ntws los ntawm lub ntsws: qhov cua nkag mus, nthuav tawm, thiab nthuav tawm. Ventilation yog txheej txheem los ntawm huab cua txav mus thiab tawm ntawm lub ntsws.
