Question: If the blood has excessively low pH; the body can correct this by:?
A. reabsorption of additional H+ by the kidneys
B. hypoventilating
C. lowering heart rate
D. absorption of additional H+ by the intestines
E. none of the above
Answers:
Low PH is acidic blood (high in acid). The body usually balances that long term by producing more HCO3 (bicarbs) or increasing breathing rate so you can get rid of more CO2. Either will higher your PH. Kidneys is the blood filter, so I do not see why that would make difference. Intestines are for digestions. O2 transfer is via the lungs through the capillary membrane, not through the intestine. Sounds like a trick question. The answer is E, unless there is some round about trick to this. Blood PH is primarily about blood oxygenation, then second, the body's compensatory mechanisms.
"A" for sure is not the answer because resorption of H+ is doing the opposite of what needs to be done...

If my research is correct, then it should be A and/or D. But what needs to be done for a low blood Ph is the consumption of foods and such with high sugar, sodium or a high acid content. This is purely because the level of hydrogen will rise as the level of hydrogen atoms consumed increases, which should, at least theoretically, regulate blood Ph levels.
