what is how is respiration regulated
Hi There,
Hope you are doing good
The respiratory rhythm Centre present in our brain which regulates the respiration . The function of the respiratory rhythm Centre are moderated by the Pneumotaxic Centre present in the pons . Chemo sensitive area which is situated adjacent to the rhythm Centre is highly sensitive to CO2 and H+ concentration.
Increasing in the concentration of these compounds can activate this chemo- sensitive area which in turn gives signal to the rhythm Centre to change the rate of expiration for the elimination of these compounds.
The receptor present in the carotid artery and aorta can also detected the levels of CO2 and H+ ions in blood.
As the level of cO2 increases, these receptors send signals to the rhythm centre to perform corrective actions.
Hope this will help
Thank you!
