As PCO2 of the blood decreases, what happens to the urine H+concentration as kidneys compensate for this change?(increase, decrease, or no change
Explain what the kidneys are doing that makes the H+concentration change in this manner, and how this change acts as acompensation to the decreasing PCO2.
As PCO2 of the blood decreases, what happens to the urine HCO3-concentration?
Explain what the kidneys are doing that makes the HCO3-concentration change in this manner, and how this change acts as acompensation to the decreasing PCO2.
Give an example of the kind of physiological change that wouldCAUSE a decrease in [H+] DIRECTLY (without causing a change in PCO2first).
What would such a condition be called?
Give an example of the kind of physiological change that wouldCAUSE an increase in [H+] DIRECTLY (without causing a change inPCO2 first).
What would such a condition be called?

1 decreases Respiration depends on sensitivity of respiratory control mechanisms to change in blood pCO2 and pH CO2 which is mildly acidic is waste from cells which is excreted into blood along with other waste products Blood carries CO2 to lungs where it is exhaled As CO2 accumulates in the blood due to decreased PCO2 the pH of blood decreases The brain control this by increasing the speed of breathing In the kidney CO2 acted upon by carbonic anhydrase combines with water to form H2CO3 See Answer
