The kidney mechanism for buffering the acidity of the blood involves the excretion of hydrogen ions and the reabsorption of bicarbonate ions when the blood is acidic. This helps to maintain a stable pH in the body. If the blood is too basic, the kidney will excrete bicarbonate ions and reabsorb hydrogen ions. However, the kidney does not perform these functions when the lung system is not working, as both systems work in coordination to maintain pH balance in the body.
