(B) The respiratory rhythm centre in the medulla region of the brain is primarily regulated by chemosensitive areas.These areas are highly sensitive to $CO_{2}$ and hydrogen ions.An increase in the concentration of $CO_{2}$ in the arterial blood stimulates these chemoreceptors,which in turn signal the respiratory centre to increase the rate of breathing to eliminate excess $CO_{2}$ from the body.
