Question

In response to $C{O}_2$ and $H^{+}$ concentration, the chemosensitive area and, receptors associated with aortic arch and carotid artery, send necessary signals for remedial action to _______________.

• A. Pneumotaxic centre
• B. Apneustic centre
• C. Respiratory rhythm centre
• D. Both A and B

Answer 1

The correct option is C Respiratory rhythm centre

C. Respiratory rhythm centre

Solution: In our body, we have significant ability to monitor and regulate the respiratory system. There are some feedback mechanism that controls our breathing rate according to the needs of our body. If the carbon dioxide concentration increases, the chemo-sensitive area and receptors associated with aortic arch and carotic arch send signal to the respiratory rhythm centre in medulla for alteration of the breathing rate.

So the correct answer is "Respiratory rhythm centre".
