NEETZoologyBreathing and Exchange of Gases
What signals the rhythm centre to make necessary adjustments in the respiratory process?
Options
- AOxygen
- BPneumotaxic Centre
- CChemosensitive Area
- DReceptors associated with aortic arch and carotid artery
Correct answer
C. Chemosensitive Area
Step-by-step solution
This is done by the neural system. A specialised centre present in the medulla region of the brain called respiratory rhythm centre is primarily responsible for this regulation. Another centre present in the pons region of the brain called pneumotaxic centre can moderate the functions of the respiratory rhythm centre. Neural signal from this centre can reduce the duration of inspiration and thereby alter the respiratory rate . A chemosensitive area is situated adjacent to the rhythm centre which is highly sensitive
