Receptors associated with aortic arch and carotid artery can recognise changes in (i) and (ii) concentration and send necessary signals to (iii) for remedial actions.

bio-chemistry cell membrane regulation of respiration transport of respiratory gases buffer and its role

  1. (i) $O _{2}$ (ii) $CO _{2}$ (iii)pneumotaxic centre

  2. (i) $CO _{2}$ (ii) $H^+$ (iii) rhythm centre

  3. (i) $CO _{2}$ (ii) $H^+$ (iii) apneustic centre

  4. (i) $O _{2}$ (ii) $H^+$ (iii)pneumotaxic centre

Show answer
Correct Option: B
Explanation:

Receptors associated with aortic arch and carotid artery can recognise a change in $CO _{2}$ and $H^+$ concentration and send necessary signals to the rhythm centre (medulla oblongata) that controls the rate of breathing.

So, the correct answer is (B).
