What is the primary function of the respiratory rhythm centre?
Options
- ATo moderate the functions of the respiratory rhythm centre
- BTo regulate the respiratory rhythm
- CTo signal the rhythm centre to make necessary adjustments in the respiratory process
- DTo recognise changes in CO₂ and H⁺ concentration
Correct answer
B. To regulate the respiratory rhythm
Step-by-step solution
Human beings have a significant ability to maintain and moderate the respiratory rhythm to suit the demands of the body tissues. 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
