Vedclass · Answer

(B) The rate and depth of respiration are primarily regulated by the respiratory rhythm center in the medulla region of the brain. This center is highly sensitive to the concentration of $CO_2$ and hydrogen ions $(H^+)$ in the blood. When the concentration of $CO_2$ increases in the blood,it leads to a decrease in blood $pH$ (acidosis). This change is detected by chemoreceptors,which send signals to the respiratory center to increase the rate and depth of breathing to eliminate excess $CO_2$ from the body. Therefore,the correct option is $B$.
