Ntshav . Tib neeg ntshav muaj a tsis pub carbonic acid (H 2CO 3thiab bicarbonate anion (HCO 3 -) kom tswj tau ntshav pH ntawm 7.35 thiab 7.45, raws li tus nqi siab dua 7.8 lossis qis dua 6.8 tuaj yeem ua rau tuag taus.

Ntawm no, dab tsi yog cov kab mob ntawm cov ntshav?

Cov tsis system ua haujlwm hauv ntshav plasma muaj xws li plasma proteins, phosphate, thiab bicarbonate thiab carbonic acid buffers . Lub raum pab tswj cov kua qaub-puag tshuav los ntawm kev tso tawm hydrogen ions thiab tsim bicarbonate uas pab tswj ntshav plasma pH nyob rau hauv ib txwm muaj.

Ib sab saum toj no, dab tsi yog qhov tsis zoo tshaj plaws hauv lub cev? Bicarbonate tsis pub yog cov feem ntau tseem ceeb tsis system hauv ntshav plasma (feem ntau nyob rau hauv cov kua dej extracellular).

Ib yam li ntawd, peb lub tshuab tsis tseem ceeb hauv tib neeg lub cev yog dab tsi?

1 Teb. Cov peb lub cev tsis zoo ntawm peb lub cev yog carbonic acid bicarbonate tsis system , phosphate tsis system thiab protein tsis system.

Lub luag haujlwm tseem ceeb ntawm phosphate tsis yog dab tsi?

Txawm tias cov phosphate buffer system tsis yog ib qho tseem ceeb-tant li cov kua dej extracellular tsis pub , ua play a lub luag haujlwm tseem ceeb hauv tsis kam lub raum tubular kua thiab intracellular kua. Thaum lub hauv paus muaj zog, xws li NaOH, ntxiv rau lub tsis system , ua OH yog buffed los ntawm H2PO4 los tsim cov HPO ntxiv4= + H2O.
