Vedclass · Answer

(D) The regulation of respiration rhythm is primarily controlled by the concentration of $CO_{2}$ and $H^{+}$ ions in the blood and cerebrospinal fluid.Chemoreceptors are highly sensitive to changes in $CO_{2}$ and $H^{+}$ levels.While $O_{2}$ is essential for cellular respiration,its role in the regulation of the respiratory rhythm is quite insignificant under normal physiological conditions because the respiratory center is not sensitive to minor fluctuations in $O_{2}$ levels.

Which of the following gases is quite insignificant for the regulation of respiration rhythm?
