2. Which organ systems function to regulate acid-base balance in body fluid?
The systems that function to regulate acid-base balance in body fluid are the Respiratory System, Urinary System, and the Digestive System. When we breathe, our lungs remove excess carbon dioxide from your body. When they cannot do so, our blood and other fluids become too acidic. As for the kidneys, they are responsible for the elimination of hydrogen ions and regeneration of bicarbonate. Finally for the liver, it plays a major role in removing the small amount of lactic acid that is produced during normal cell metabolism. (Higgins, 2004)
