Assertion: Chemosensitive area is situated adjacent to l the rhythm centre which ishighly sensitiveo CO_(2) and 1 hydrogen ions. Reason: Receptors associated with aortic arch and carotidis artery can recognise changes in O_(2)" and "H^(+) concentration and send necessary signals to the rhythm centre for remedial actions.

Which of the following statements are CORRECT ? I. A specialized center present in the medulla region of the brain called respiratory rhythm center is primarily responsible for the regulation of respiration. II. A Chemosensitive area is situated adjacent to the rhythm which is highly sensitive to O_2,CO_2 and hydrogen ions . III . Receptors associated with aortic arch and carotid artery also can recognize changes in CO_2 and H^+ concentration and send necessary signals to the rhythm center for remedial actions. IV The neural signal from the pneumatic center can increase the duration of inspiration and thereby alter the respiratory rate .
