  • Inhalation&nbsp;1/5name the muscles involved and the action they perform

    Inhalation 1/5

    name the muscles involved and the action they perform

    diaphragm contracts and moves inferiorly

    external intercostals contract and elevates ribs and sternum

  • Inhalation&nbsp;2/5

    Inhalation 2/5

    thoracic cavity volume increases

  • Inhalation&nbsp;3/5

    Inhalation 3/5

    Lungs are stretched

    increases intrapulmonary volume

  • Inhalation&nbsp;4/5

    Inhalation 4/5

    Intrapulmonary pressure drops to -1 mm Hg

  • Inhalation&nbsp;5/5

    Inhalation 5/5

    gasses flow into lungs down the pressure gradient until intrapulmonary pressure is 0 and equal to atmospheric pressure

  • Expiration&nbsp;1/5name the muscles involved and the action they perform

    Expiration 1/5

    name the muscles involved and the action they perform

    diaphragm relaxes moves superiorly

    external intercostals relax and depresses ribs and sternum

  • Expiration&nbsp;2/5

    Expiration 2/5

    thoracic cavity volume decreases

  • Expiration&nbsp;3/5

    Expiration 3/5

    elastic lungs recoil passively and decreases intrapulmonary volume

  • Expiration&nbsp;4/5

    Expiration 4/5

    intrapulmonary pressure rises to +1mm Hg

  • Expiration&nbsp;5/5

    Expiration 5/5

    Gasses flow out the lungs down the pressure gradient until the intrapulmonary pressure is 0 and equal to atmospheric pressure
