Final answer:

The body has several mechanisms for regulating pH, including buffers, breathing, and excretion of chemicals in urine.

Step-by-step explanation:

The body has several mechanisms for regulating pH, including breathing, excretion of chemicals in urine, and the release of chemicals called buffers into body fluids. Buffers are solutions of weak acids and their conjugate bases that can neutralize small amounts of acids or bases in body fluids. When there is a decrease in the pH of a bodily fluid, buffers act as weak bases and bind excess hydrogen ions. Conversely, when the pH rises, buffers act as weak acids and contribute hydrogen ions.

C02 regulation, the carbonic acid-bicarbonate buffer regulation, H+ regulation, and gas exchange. These regulations are all done through the circulatory, excretory, and respiratory systems. They are all part of one big function, that is homeostasis.
