Explanation

(A) The lungs are responsible for regulation of CO2, and this parameter primarily reflects respiratory function. (B) CO2 content of the blood is an indirect measure of respiratory function. (C) HCO3 is a measure of kidney function only and is important in acid-base balance. (D) Base excess represents the excess of HCO3 and is not reflective of respiratory function.
