Question

what are examples of buffer systems in the human body

Answer 1

one of the examples is blood.red blood cells have an enzyme that cause this reaction
\[H _{2}O+CO _{2}\rightarrow HCO _{3}^{-}+H ^{+}\]
This reaction is reversible so
\[H _{2}O+CO _{2}\leftarrow HCO _{3}^{-}+H ^{+}\]
If the H concentration in blood begins to fall (that is, if pH rises), the reaction proceeds to the right and more carbonic acid dissociates, replenishing hydrogen ions
But when H concentration in blood begins to rise (when pH drops), the reaction proceeds to the left, with HCO3 (the base) removing

Answer 2

oh snap! awesome answer bro!
