Explain regulation of respiration ( class 11 ) |
| Answer» REGULATION OF RESPIRATION\tA specialised centre present in the medulla region of the brain called\xa0respiratory rhythm centre\xa0is primarily responsible for this regulation.\tAnother centre present in the pons region of the brain called\xa0pneumotaxic centre\xa0can moderate the functions of the respiratory rhythm centre.\tNeural signal from this centre can reduce the duration of inspiration and thereby alter the respiratory rate.\tA chemosensitive area is situated adjacent to the rhythm centre which is highly sensitive to CO2\xa0and hydrogen ions.\tReceptors associated with aortic arch and carotid artery also can recognise changes in CO2\xa0and H+\xa0concentration and send necessary signals to the rhythm centre for remedial actions. | |
