Introduction:

An increase in the carbon dioxide level is detected with the help of chemoreceptors that are present in the medulla oblongata. A fall in the pH due to increased carbon dioxide levels decrease the parasympathetic stimulation and increases sympathetic stimulation. This also results in an increase in heart rate and force of contraction that increases the cardiac output and helps the lungs to exhale more carbon dioxide.
