An individual’s blood pH level is 7.3. How will her body most likely respond?

A blood pH of 7.3 is below the normal range of about 7.35–7.45, so the blood is too acidic. The kidneys help correct this by removing acid and conserving or releasing bicarbonate, which helps raise the blood’s pH. Therefore, the best answer is D, that her kidneys will release substances to neutralize the blood.
