What is the role of the respiratory rhythm centre in regulating the respiratory system?
Options
- AIt regulates the oxygen levels in the blood
- BIt controls the rate of breathing
- CIt controls the depth of breathing
- DIt controls the pattern of breathing
Correct answer
B. It controls the rate of breathing
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
