What is the renal response when acid is liberated into the body?

The renal response to acid liberation involves several physiological mechanisms aimed at maintaining acid-base balance. In the context of increased acidity in the body, the kidneys play a crucial role in compensating for this change by regulating the excretion and production of various substances.

Specifically, when acid is liberated into the body, the kidneys will increase the production and excretion of ammonia. This is because ammonia can combine with hydrogen ions (which represent excess acid) to form ammonium ions, which are then excreted in the urine. This reaction effectively helps to neutralize excess acid in the bloodstream, facilitating the maintenance of proper pH levels.

The production of bicarbonate is also increased in response to acid, but the direct response to liberating acid emphasizes the importance of ammonia in excreting excess hydrogen ions. The other options describe processes that do not facilitate the immediate renal response to excess acid liberation effectively.
