A buffer yog ib qho txheej txheem uas tiv thaiv kev hloov pauv hauv pH. Lub cev tsis muaj zog siv ncaj qha tshem tawm cov kua qaub, cov hauv paus, lossis carbon dioxide los ntawm lub cev txhawm rau kho cov kab mob acidity.
Yuav ua li cas tswj pH sai tshaj plaws?
Cov pa roj carbonic acid-bicarbonate buffer system yog qhov nrawm tshaj plaws ntawm tag nrho cov txheej txheem them nyiaj.
Puas yog lub plab zom mov puas yog lub cev tsis muaj zog?
Ib lub cev tsis muaj zog yog lub cev, uas yog lub plab zom mov, uas tswj cov pH los ntawm kev tswj lub cev cov kua qaub, cov hauv paus, lossis CO2. Lub raum tubules secrete H + rau hauv cov kua dej tubular, uas feem ntau ntawm nws khi rau bicarbonate, ammonia, thiab phosphate buffers.
Dab tsi yog cov tshuaj tsis zoo hauv lub cev?
Peb lub cev tsis zoo ntawm peb lub cev yog carbonic acid bicarbonate buffer system, phosphate buffer system thiab protein buffer system.
Dab tsi yog qhov tseem ceeb tshaj plaws ntawm lub cev tsis sib xws?
Cov kab mob bicarbonate tsis zoo yog thawj qhov tsis sib xws rau ECF.
