Comparison of the oxyhemoglobin and 'CO2 equilibrium curves. The carrying capacity for CO2 is much greater than for O2. The increased steepness and linearity of the CO2 equilibrium curve allow the lungs to remove large quantities of CO2 from the blood with a small change in CO2 tension. a = gas content in arterial blood; v = gas content in mixed venous blood.
