Explanation:This question explores understanding of pH further, in a different context. Candidates need to think carefullyabout the cause and response to deviations in homeostasis.pH is lower than healthy people.Blood is tending towards being too acidic. Basic HCO3- is high, indicating kidneys are attempting tocorrect the situation. CO2 is high, which is driving the acidity. Therefore gas exchange in the lungs isimpaired.See aboveBlood is tending towards alkali. CO2 is high, indicating the lungs are attempting to correct the situation.HCO3- is high, suggesting that the kidneys are producing too much, or that stomach acid has been lost (anet loss of H+ from the body), and replacing it has favoured an increase of HCO3- in the blood. (seeequilibria from previous question).
