Episode notes
Brain Rhythm That Starts Every Breath
- The pre-Bötzinger complex in the brainstem initiates every breath by activating motor neurons to the diaphragm and intercostals.
- Inspiration ends when that neuronal burst stops and passive recoil drives exhalation.
Separate Circuit For Active Expiration
- A separate oscillator around the facial nucleus drives active expiration during exertion or forced exhalation.
- Mammals uniquely evolved a diaphragm, enabling efficient inspiration and high lung surface area.
Diaphragm Enables Massive Lung Surface Area
- Mammals pack ~400–500 million alveoli to create a huge surface area for gas exchange within a small chest.
- The diaphragm's mechanical advantage expands that membrane with minimal effort to sustain oxygen delivery.
