- Breathing
- Expiration (passive= no energy required)
- Intercostals and diaphragm relax
- Ribcages moves down and in
- Thorax volume decreases
- Lung pressure increases
- Air forced out
- Lung pressure increases
- Thorax volume decreases
- Ribcages moves down and in
- Intercostals and diaphragm relax
- Inspiration (requires energy)
- Intercostals and diaphragm contract
- Ribcage move up and out
- Diaphragm flattens, thorax volume increases
- Lung pressure decrease
- Air leaves lungs
- Lung pressure decrease
- Diaphragm flattens, thorax volume increases
- Ribcage move up and out
- Intercostals and diaphragm contract
- Spirometer
- Tidal= Volume of air in each normal breath
- Vital= max volume that can be breather in/out
- Residual= can't be breathed out
- Expiration (passive= no energy required)
