How is respiration regulated?

Explanation

A specialised respiratory centre present in the medulla oblongata of the hind brain called respiratory rhythm centre is responsible for this regulation . Pneumotaxic centre present in pons varoli region of the brain moderatesthe function of the respiratory rhythm centre to ensure normal breathing . The chemosensitive area found close to the rhythm centre is highly sensitive to `CO_2` and `H^(+)` and `H^(+)` are eliminated out by respiratory process . Receptors associated with the aortic each and carotid artery send necessary signals to the rhythm centre for remedial action . The role of `O_2` is insignificant in the regulation of respiratory rhythm.
