Vedclass · Answer

(D) The chemosensitive area is located adjacent to the respiratory rhythm centre in the medulla oblongata of the brain.This area is highly sensitive to changes in the concentration of $CO_{2}$ and $H^{+}$ ions in the blood.An increase in $CO_{2}$ and $H^{+}$ concentrations activates this chemosensitive area,which in turn signals the rhythm centre to make necessary adjustments in the respiratory process to eliminate these substances.Since $CO_{2}$ concentration influences blood $pH$ by forming $HCO_{3}^{-}$ and $H^{+}$ ions (facilitated by the enzyme carbonic anhydrase),both $CO_{2}$ and $H^{+}$ are critical factors for this regulation.
