the most important physiological buffer systems are the lungs and
Others bind hydrogen ions when the environment becomes too acidic, thus raising pH balance to normal levels. Physiological buffers-systems that control the body's output of acids, acid bases, or carbon dioxide. The body's two main physiological buffers are the urinary system and the respiratory system.Of all the buffer systems, the urinary system buffers the greatest quantity of acid.It is quite slow, however, as it requires several hours to days to respond to changes in acidity.thers bind hydrogen ions when the environment becomes too acidic, thus raising pH balance to normal levels.
