  1. what does the Pharynx and larynx do
    connect the trachea
  2. what does the trachea split into
    right and left bronchi
  3. what does the bronchi split into
    bronchioles
  4. what does the Mucociliary apparatus do
    protective mechanism, moves object up so it can be coughed out
  5. what lines the bronchi and what are they
    columnar epithelial cells, has cilia and excrete mucus from goblet cells
  6. what happens in the Turbinates
    place where air is wormed and humidified
  7. What type of muscle is in the bronchial walls?
    smooth muscle fiber
  8. What are the alveoli: what are they covered in and what happens there?
    Alevli, grape like clusters lined with surfactant, uses surface tension to keep lung open
  9. What causes bronchoconstriction or bronchodilation?
    bronchoconstriction is caused by parasympathetic stimulation, bronchodilation is caused by sympathetic stimulation
  10. What are the 4 main functions of the respiratory system
    Oxygen-carbon dioxide exchange, Regulation of acid-base balance, Body temperature regulation, Voice production
  11. what are the four ways the respiratory system works
    Ventilation, Distribution, Diffusion, Perfusion
  12. What are the major defense mechanisms in the respiratory system?
    Nasal cavity turbinates, Protective reflexes, Mucociliary clearance
  13. What are the 3 main ways to treat respiratory disorders?
    Control secretions, Control reflexes, Maintain normal airflow to alveoli
  14. What is the difference between a nebulizer and an inhaler?
    nebulizer is Smaller particles that go further into the system,  inhaler is Particles to the upper airway
  15. How do expectorants work?
    makes it easier for the mucous to be removed
  16. How do bronchodilators work?
    relaxes the muscle in the lungs and widens the airways to make it easier to breath.
  17. What is a mucolytic?
    breaks up mucous in lungs to make it easier to breath
  18. when do you use antitussives?
    when the cough is non productive
  19. Why would you use steroids in the respiratory system?
    steroids have a strong anti inflammatory effect when given as a inhalant
