Buffer is an aqueous solution that resists changes in pH when acids or
bases are added to it. A buffer solution is typically composed of a weak

the phosphate buffer system, and the plasma protein buffer system. Of
the three buffer systems, the bicarbonate buffer system is arguably the
most important as it is the only one that is coupled to the respiratory
system
