Quantitatively, the most important is the bicarbonate buffer system, since 1) it is present in high concentrations in both intra- and extracellular fluids, and 2) it maintains an equilibrium between metabolically-generated acid (H3O+), CO2, which can be rapidly eliminated through respiration, and HCO3-, whose excretion is controlled over longer time periods by the kidneys.
