  • 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…
