When travelling high altitude, one of the problem is alkalosis of the blood. Remember the equation for acid balance: CO2 + H2O ⇌ H2CO3 ⇌ HCO3− + H+ If there is a low amount of CO2 outside, then greater CO2 than normal will diffuse out of the lungs. This will cause the blood to become more basic. To counteract the problem, a drug may be taken to both lower the blood pressure and help correct the pH. To do this, it blocks a symporter of HCO3- and Na+ in the proximal tubule of the kidney. Q: How would blocking transport of HCO3- help to lower the pH of the blood?
