Vedclass · Answer

(A) The rate of respiration is primarily regulated by the respiratory rhythm center located in the medulla oblongata of the brain. This center is highly sensitive to the concentration of $CO_2$ and hydrogen ions $(H^+)$ in the blood. An increase in the concentration of $CO_2$ and $H^+$ ions activates the chemosensitive area,which in turn signals the respiratory rhythm center to increase the rate of inspiration and expiration to eliminate excess $CO_2$. Therefore,$CO_2$ concentration is the primary factor that directly affects the rate of respiration.
