REGULATION OF RESPIRATION

  • A specialised centre present in the medulla region of the brain called respiratory rhythm centre is primarily responsible for this regulation.
  • Another centre present in the pons region of the brain called pneumotaxic centre can moderate the functions of the respiratory rhythm centre.
  • Neural signal from this centre can reduce the duration of inspiration and thereby alter the respiratory rate.
  • A chemosensitive area is situated adjacent to the rhythm centre which is highly sensitive to CO2 and hydrogen ions.
  • Receptors associated with aortic arch and carotid artery also can recognise changes in CO2 and H+ concentration and send necessary signals to the rhythm centre for remedial actions.
