Question:
Which of the following moderate the functions of the respiratory rhythm to suit the demands of the body tissue?
Which of the following moderate the functions of the respiratory rhythm to suit the demands of the body tissue?
Show Hint
Pneumotaxic centre (pons) limits inspiration duration; Apneustic centre prolongs inspiration; Medullary centre sets the basic rhythm.
Updated On: May 26, 2026
- Alveolar cavity of lungs
- Carbamino haemoglobin of blood
- Pneumotaxic centre of pons region of brain
- Thorax
Show Solution
Verified By Collegedunia
The Correct Option is C
Solution and Explanation
Step 1: Concept
Neural regulation of respiratory rhythm.
Step 2: Meaning
The respiratory centre in the brainstem controls and modulates the rate and depth of breathing.
Step 3: Analysis
The pneumotaxic centre in the pons modulates the output of the medullary rhythmicity centre, limiting inspiratory duration and adjusting respiratory rate to match metabolic demands. The other options (alveoli, carbamino-Hb, thorax) are structural or chemical components, not modulatory control centres.
Step 4: Conclusion
The pneumotaxic centre of the pons moderates respiratory rhythm to match body tissue demands. Final Answer: (C)
