Which of the following gases is quite insignificant for the regulation of respiration rhythm?
1 \(\mathrm{CO}_{2}\)
2 \(\mathrm{N}_{2}\)
3 \(\mathrm{H}^{+}\)
4 \(\mathrm{O}_{2}\)
Explanation:
The role of oxygen in the regulation of respiratory rhythm is quite insignificant.

An area situated adjacent to the respiration rhythm centre is highly sensitive to
1 \(\mathrm{CO}_{2}\)
2 Hydrogen ions
3 \(\mathrm{CO}_{2}\) and Hydrogen ions
4 Oxygen only
Explanation:
A chemosensitive area is situated adjacent to the rhythm centre which is highly sensitive to \(\mathrm{CO}_{2}\) and hydrogen ions. Increase in these substances can activate this centre, which in turn can signal the rhythm centre to make necessary adjustments in the respiratory process by which these substances can be eliminated.

Inspiratory centre is located in
1 Medulla oblongata
2 Cerebellum
3 Hypothalamus
4 Cerebrum
Explanation:
Inspiratory centre is located in medulla oblongata.

Human beings have a significant ability to maintain and moderate the respiratory rhythm to suit the demands of the body tissues. This is achieved by
1 Arterial system
2 Endocrine system
3 Neural system
4 Neural and endocrine system
Explanation:
Neural system in humans regulates and moderate the respiratory rhythm. A specialised respiratory centre is located in the medulla oblongata and another in pons Varoli. These centres regulate the rate and the depth of breathing by controlling the contraction of diaphragm and other respiratory muscles.
