Vedclass · Answer

(C) The regulation of respiration is controlled by the respiratory rhythm centre located in the medulla region of the brain. Chemosensitive areas are situated adjacent to the rhythm centre, which are highly sensitive to $CO_{2}$ and $H^{+}$ ions. Receptors associated with the aortic arch and carotid artery also recognize changes in $CO_{2}$ and $H^{+}$ concentration and send necessary signals to the rhythm centre for remedial actions to maintain homeostasis.

Receptors associated with the aortic arch and carotid artery can recognize the changes in $A$ and $H^{+}$ concentration and send necessary signals to the $B$ for remedial actions. Select the right choice for $A$ and $B$ to complete the given $NCERT$ statement.
