Hello Maam, I have a doubt. Increased PCO2 will cause more CO2 to combine with H2O and produce H2CO3. H2CO3 ↔ H+ + HCO3-. Why will this decrease pH when HCO3- is also produced along with H+ ? Shouldn't pH remain same ?
Extremely good question. I ask this question to students. Well H2CO3 is weak acid. Doesn’t dissociate completely releasing very less acids. While other acids are strong releasing lot of H+ Also yes when pco2 increases, direction of reaction proceeds to release more H+. And that’s why increased pco2 decreases ph if it is not being expelled equally
If you are aware of Physiology basics, directly move to
04:45 , and check out whether you can solve the scenarios
U r the best teacher on whole u tube for mbbs student. Please upload more and more videos .
Thanks 🙏
Will surely do
Thank you maam
Most welcome
Madam need a kidney failure vedio also, nice explanation 😊
Yeah sure
