1. Assume your blood has a pH of 7.4 and you have been producing urine with a pH of 7.4 for a while. You drive to very high altitude (ca. 4,000 m) and spend several hours there. Your alveolar ventilation rate increases (as expected), and eventually this causes your blood pH to rise above 7.4 (your blood plasma becomes more basic than normal). \newline This change in blood pH will initiate compensatory homeostatic mechanisms in your kidneys ("renal compensation") that...
