Vedclass · Answer

(B) The rate of respiration is primarily regulated by the concentration of $CO_2$ and $H^+$ ions in the blood.Chemosensitive areas situated adjacent to the rhythm centre are highly sensitive to $CO_2$ and hydrogen ions.An increase in these substances can activate this centre,which in turn can signal the rhythm centre to make necessary adjustments in the respiratory process by which these substances can be eliminated.Therefore,the rate of respiration is directly proportional to the concentration of carbon dioxide in the blood.

The rate of respiration is directly proportional to:
