Vedclass · Answer

(C) The chemosensitive area is highly sensitive to chemicals and is located adjacent to the rhythm centre in the medulla oblongata.This area contains chemoreceptors that are specifically sensitive to increased concentrations of $CO_2$ and $H^+$ ions.When the levels of $CO_2$ and $H^+$ ions rise in the blood and body fluids,they stimulate this chemosensitive area.This stimulation then sends signals to the rhythm centre to make necessary adjustments in the respiratory process to eliminate these excess substances.

Which substances when present in high level can activate the chemosensitive area present adjacent to the rhythm centre?
