Answer to Question 1

ANS: B
Note that the pH is determined by the ratio of HCO3 to dissolved CO2, rather than by the ab-solute values of these components. As long as the ratio of HCO3 buffer to dissolved CO2 is 20:1, the pH is normal, or 7.40.

Answer to Question 2

ANS: D
After all available HCO3 ions react with H+ ions, the remaining H+ ions react with two other fil-trate buffers, phosphate and ammonia, as illustrated in Figures 13-4 and 13-5.
