Essential Processes & Mechanisms
Gas Exchange:
- Diffusion principles
- Partial pressure gradients
- Transport of gases (O2 & CO2)
- Hemoglobin role
Breathing Mechanism:
- Inspiration:
- Diaphragm contraction
- External intercostal muscle action
- Volume increase
- Pressure decrease
- Expiration:
- Diaphragm relaxation
- Internal intercostal muscle action
- Volume decrease
- Pressure increase
