  1. Pressure and volume are related in inverse/opposite ways. This is known as
    Boyle's Law
  2. __________ due to the weight of the air, is the pressure that moves air into the lungs.
    Atmospheric pressure
  3. Sea level air pressure = 760 mm Hg= 760____ =1 atmosphere
  4. If pressure inside the lungs and alveoli decreases, atmospheric pressure pushes air in. This is:
  5. The diaphragm is stimulated by the ______ nerves.
  6. When this is stimulated, the thoracic cavity enlarges, the intra-alveolar pressure falls below atmospheric pressure and air is forced in.
  7. The moist inner surface of alveoli attract each other, and creates ______ ____ , making it difficult for the alveoli to inflate and can collapse them.
    Surface Tension
  8. Lipoproteins secreted into alveolar that reduce the alveoli's tendency to collapse, and is essential for new-born lungs to inflate.
  9. D/t the elastic tissue of the lungs and it's stretching during inspiration
    Elastic recoil
  10. Forces responsible for _______ come from elastic recoil and surface tension.
  11. As the volume in a container is increased, the pressure in the container will decrease, and vice-versa.
    Boyle's Law
  12. Neuron groups in the brainstem that initiate impulses to control breathing
    Respiratory Areas
  13. Includes 2 neuron respiratory groups that extend the length of the medulla: the ventral and dorsal respiratory gruops
    Medullary Rhythmicity Center
  14. The basic rhythm of breathing arises from this medullary respiratory group
    Ventral Respiratory Group
  15. Inspiratory muscles, primarily diaphragm, are stimulated by this medullary respiratory group that cotribute to forceful breathing
    Dorsal respiratory group
  16. This neuron group assists the rhythm of breathing by limiting inspiration.
    Pontine Respiratory Group
