Respiratory

• Ventilation


  breathing
• Gas exchange

  oxygen moves from ,lungs to blood stream
• Gas transport


  btw lungs
• What are the organs of the respiratory system

  Nose, Nasl cavity, pharynx, epiglottis, larynx, trachea, bronchi, bronchioles, diaphargm
• function of pharynx

  passage way for food and way
• larynx


  top of trachea
• trachea


  passageway for air
• The right lung has 3 lobes and the left lung has 2
• where is the pleural cavity found

  btw visceral
• expansion during inspiration

  diaphragm moves up and out
• expiration

  diaphragm moves down and in
• which forces normal expiration

  surface tension
• inspiratory reserve volume


  Additional air after normal breathing
• expiratory


  volume expelled during forced exhalation beyond Tv
• Residual volume


  air that remains after exhalation
• vital capacity

  maximum hair you can exhale after inhaling
• Total lung capacity

  biggest inhale and exhale
• tidal volume


  volume of air that can enter a normal cycle
• inspiratory capacity


  maximum air that be inhale
• How does hyperventilation decrease the respiratory rate

  decreased CO2 In blood
• which direction do gasses diffuse

  Higher pressure to lower pressure
• Partial pressure


  steeper heart rate up
• medulla oblongata


  dorsal: sensory

  ventral: basic rhythm of breathing
