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 .

Complete the following sentence by selectrin the correct option. Receptors associtated with aortic arch and carotid artery can recognise changes in overset((i))"______" and overset((ii))"______" concentration and send necessary signals to overset((iii))"______" for remedial actions.

Chemosensitive area of respiratory centre in medulla is affected of both CO_(2) and H^(+) ions.

Go through the following statements (i) the peripheral chemoreceptors for regulation of respiration are located in carotid veins and arch of aorta (ii) the primary effect of penumotaxic centre is to control the switch off point of inspiratory signal and thus limit inspiraton (iii) the chemosensitve area fo brain for respiratory control is highly sensitive to O_(2) concentration (iv) i case of feital haemoglobin the oxygen haemoglobin dissociation curve is shifted toward left ltrbgt which of these ar correct ?
