- respiratory system includes the lungs
The function of the respiratory system:
- get oxygen into the body
- expel carbon dioxide from the body
- less oxygen needed at rest because muscles are not working as hard
- more air taken in during exercise - more oxygen for muscles to produce energy
- more efficient respiratory system - provide muscles with oxygen for longer
- regular exercise will improve lung capacity - more oxygen taken in with each breath
- gaseous exchange in alveoli - gas diffusion
Respiratory system measurements:
- tidal volume - the amount of air inspire and expired with each normal breath at rest/during exercise
- vital capacity - the amount of air that can be expired after inspiring as deeply as you can
- breathing rate…
