Role of Kidney in Acid Base Balance of the Body.

 

Introduction.

  • Kidneys along with lungs play a major role in acid base balance of the body.

  • Lungs are very fast but capacity is limited while kidneys are comparatively slower but their capacity is very high.

  • Lungs maintain acid base balance by converting HCO3 ions to Co2 which is exhaled.

  • Kidneys largely reabsorb Na+ ions in exchange of H+ ions which are excreted in urine and imparts acidity to urine.

  • The H+ ions are also excreted in the form of NH4+ and Hydrogen Phosphate Salts.

  • The H+ ions are formed by help of “Carbonic Anhydrase” enzyme in cells as well as lumen of Renal tubule as,
