a substance which is able to resist change in the pH of a solution so that the pH remains constant
a solution which will maintain body pH due to the release or absorption of hydrogen ions to balance any loss or gain. Carbon dioxide only partially dissolves in solution, and this means that it can act as a buffer. If more hydrogen is present then it will be combined with bicarbonate and converted to water and carbon dioxide. Water will be lost through the kidneys and carbon dioxide will be lost in exhaled air. Alternatively, if metabolic alkalosis is present, then carbon dioxide will be combined with water and converted to bicarbonate and hydrogen ions, to maintain the pH.
