How does the respiratory system control carbonic acid concentration and pH?
when there is to much carbonic acid the body increases rate and depth of respiration to reduce the co2, which reduces the carbonic acid,( water in the plasma + co2 = h2co3 . when the co2 level goes down below normal levels, respirations slow and become more shallow to retain co2 which increases the carbonic acid, and adjusts the blood ph.
