2 Cerebrum
3 Medulla oblongata
4 Crura cerebri
BIOXI17: BREATHING AND EXCHANGE OF GASES

338788 Neural signal from which centre can reduce the duration of inspiration is (Inspiration inhibition)

1 Chemosensitive area
2 Respiratory rhythm centre
3 Receptors associated with aortic arch and carotid artery
4 Pneumotaxic centre
BIOXI17: BREATHING AND EXCHANGE OF GASES

338789 Assertion :
A chemosensitive area is situated adjacent to the rhythm centre which is highly sensitive to \(\mathrm{CO}_{2}\) and hydrogen ions.
Reason :
The role of oxygen in the regulated of respiratory rhythm is quite insignificant.

1 Both Assertion and Reason are correct and Reason is the correct explanation of the Assertion.
2 Both Assertion and Reason are correct but Reason is not the correct explanation of the Assertion.
3 Assertion is correct but Reason is incorrect.
4 Both Assertion and Reason are incorrect

338790 The respiratory process is regulated by respiratory rhythm centre present in medulla of the brain, which is?

1 Stimulated by lower \(\mathrm{O}_{2}\) and \(\mathrm{H}^{+}\) concentration in aortic arch
2 Stimulated by higher \(\mathrm{CO}_{2}\) and higher \(\mathrm{H}^{+}\) concentration.
3 Inhibited byhigher \(\mathrm{O}_{2}\) and \(\mathrm{H}^{+}\)concentration
4 Stimulated by lower \(\mathrm{O}_{2}\) and \(\mathrm{H}^{+}\) concentration in carotid artery
