Ways of breathing

Slide 1 - Tekstslide

Thoracic inhalation:
  1. intercostal muscles contract
  2. ribs move up
  3. ribs pull the pleural membrane open
  4. pleural membrane pulls open the lungs
  5. air is sucked into the lungs

Slide 2 - Tekstslide

Thoracic exhalation:
  1. intercostal muscles relax
  2. ribs move down
  3. ribs push the pleural membrane closed
  4. pleural membrane pushes closed the lungs
  5. air is pushed out of the lungs

Slide 3 - Tekstslide

Abdominal inhalation:
  1. abdominal muscles contract
  2. the diaphragm moves down
  3. the diaphragm pulls the pleural membrane open
  4. pleural membrane pulls open the lungs
  5. air is sucked into the lungs

Slide 4 - Tekstslide

Abdominal exhalation:
  1. abdominal muscles relax
  2. the diaphragm moves up
  3. the diaphragm pushes the pleural membrane closed
  4. pleural membrane pushes closed the lungs
  5. air is pushed out of the lungs

spirometer
measures long volume, but which one?
tidal volume: volume of air you breathe in or out
vital capacity: when you exhale as much as you can
residual volume: what's left after you exhale as much as you can
lung volume: vital + residual volume
