Unformatted text preview: 3-] to [CO 2 ] be? Where did this number come from? 9. Why is hemoglobin a good buffer? Why is phosphate a good buffer? (Hint: think pKa’s and amounts in the body). 10. What are the relative contributions to buffering in your body from the three buffering systems? 11. How do your lungs manipulate pH? What are the relationships between ventilation, alveolar P CO2 , plasma P CO2 , [H + ], and pH? 12. What happens to hydrogen ions and bicarbonate in the tubules of the nephron? How does this differ between the proximal and distal tubules? 13. What are the four categories of acid-base disturbances? What are the causes, consequences (in terms of pH), and compensatory responses for each?  Use Chapter 19, pp. 556-564, and Chapter 17, pp. 502-504 of Stanfield and Germann as well as your lecture notes and tutorial sessions to answer these as completely as possible....
