Rhythmicity of respiration is maintained by:
Correct answer: C. Pons
- A. The cardiac center
- B. Ventilation center
- C. Pons
- D. Carotid sinus
Explanation
The rhythmicity of respiration is primarily maintained by the respiratory centers located in the pons region of the brainstem. In the pons, the pontine respiratory group includes two areas known as the pneumotaxic center and the apneustic center. The respiratory center is responsible for generating and maintaining the rhythm of respiration, and also of adjusting this in homeostatic response to physiological changes.

About Human Respiratory System
The human respiratory system conducts air to the alveoli, where oxygen and carbon dioxide exchange occurs across thin respiratory surfaces. Questions cover the nasal passage, trachea, bronchi, lungs, diaphragm and intercostal muscles, ventilation mechanics and gas transport, while distinguishing breathing and gaseous exchange from cellular respiration.
