ProcessIntroductory
What physiological process begins with impulses from the respiratory center in the brain during inspiration?
The physiological process that begins with impulses from the respiratory center in the brain during inspiration is the movement of air into the lungs. This process involves the stimulation of the diaphragm and chest cavity expansion, which decreases intraalveolar pressure and allows air to flow into the respiratory tract.
Key points
- Inspiration is initiated by impulses from the respiratory center in the brain.
- These impulses stimulate the diaphragm and intercostal muscles.
- The diaphragm moves downward, expanding the chest cavity.
- This expansion decreases intraalveolar pressure, allowing air to enter the lungs.
