4 Both Assertion and Reason are incorrect
BIOXI17: BREATHING AND EXCHANGE OF GASES

338797 The area found adjacent to the rhythm centre in the brain is highly sensitive to the increased concentration of \(\mathrm{CO}_{2}\) and hydrogen ions is ____ in nature

1 Thermosensitive
2 Barosensitive
3 Touch sensitive
4 Chemosensitive
BIOXI17: BREATHING AND EXCHANGE OF GASES

338798 The most important afferent (sensory) receptors for the respiratory response to systemic arterial carbon dioxide are the

1 \(\mathrm{CO}_{2}\) receptors of the aortic and carotid bodies
2 \(\mathrm{H}^{+}\)receptors of the aortic and carotid bodies
3 \(\mathrm{CO}_{2}\) receptors in the medulla of the brain
4 \(\mathrm{H}^{+}\)receptors in the medulla of the brain

338799 A. Increase in \(\mathrm{CO}_{2}\) and hydrogen ions can activate chemosensitive area, which in turn can signal the rhythm centre to make necessary adjustments
B. Increase in \(\mathrm{CO}_{2}\) and hydrogen ions can activate rhythm centre, which in turn can signal the chemosensitive area to make necessary adjustments

1 A is correct
2 B is correct
3 Both are correct
4 None are correct
