Vedclass · Answer

(B) The respiratory rhythm center in the medulla region of the brain is primarily responsible for the regulation of respiration.Chemosensitive areas situated adjacent to the rhythm center are highly sensitive to $CO_2$ and hydrogen ions.An increase in the concentration of $CO_2$ and hydrogen ions in the blood activates these chemoreceptors,which in turn signal the rhythm center to make necessary adjustments in the respiratory process to eliminate these substances.Therefore,an increase in $CO_2$ concentration in the arterial blood is the primary stimulus for the respiratory centers.
