What is the role of your kidneys in compensating for low levels of oxygen
TEA [102]

Explanation:

When there are low oxygen levels in blood, the blood pH tends to lower. This is because there is an increased level of carbon dioxide in the blood that is converted to carbonic acid by carbonic anhydrase. When carbon acid dissociates, into H⁺ and HCO₃⁻ . The H⁺ influences the increase in acidity of the blood.   The kidneys will excrete most of the H⁺ and retain most of the HCO₃⁻ to help maintain the right blood pH. However, most of blood pH homeostasis is maintained largely by the lungs.
