when the chemosensitive areas in the medulla oblongata detect an increase in hydrogen ions and carbon dioxide concentration in the cerebrospinal fluid, they signal the respiratory areas to respiratory rate and tidal volume.

While the chemosensitive regions withinside the medulla oblongata locate an growth in hydrogen ions and carbon dioxide attention within side the cerebrospinal fluid, they sign the breathing regions to breathing charge and tidal volume increases.

Chemo sensitive is located adjoining to the rhythm center that is incredibly touchy to CO2 and hydrogen ions. The growth in those materials can prompt this center, which in flip can sign the rhythm Centre to make important changes in the breathing procedure through which those materials may be eliminated.

Both CO2 and H+ are a lot smaller than O2 molecules, permitting them less difficult get to to the chemoreceptors. Since carbon dioxide and hydrogen ion are transported withinside the blood as CO2 and H+, and given that O2 is sure to hemoglobin, the loose CO2 and H+ are higher capable of stimulate chemoreceptors.
