Across
  1. 1. amount of air that can be forcibly taken in over the tidal volume
  2. 6. a part of emphysema (a respirary disorder), discoloration due to poor circulation and inadequate oxygenation of the blood
  3. 7. the center of the larynx, (vocal chords)
  4. 12. a dome-shaped muscular partition separating the thorax from the abdomen in mammals. It plays a major role in breathing, as its contraction increases the volume of the thorax and so inflates the lungs.
  5. 14. amount of air that can be forcibly exhaled after tidal expiration
  6. 15. the total amount of exchangeable air
  7. 19. gas exchange between blood and tissue cells in the systemic capillaries
  8. 21. the absence of oxygen
  9. 22. diaphragm and external intercostal muscles contract, size of thoracic cavity increases,air is sucked into the lungs
  10. 23. the area where gas exchanges between the alveoli and blood occurs in the lungs
  11. 24. consists of all of the structures that provide passageways for air to travel into and out of the lungs: the nasal cavity, pharynx, trachea, bronchi, and most bronchioles.
Down
  1. 2. gas exchange between pulmonary blood and alveoli, oxygen is loaded into the blood & CO2 is unloaded from the blood
  2. 3. (a lipid molecule) coats gas-exposed alveolar surfaces
  3. 4. the soft sounds of air filling alveoli
  4. 5. increased respiratory rate, often due to extra oxygen needs (exercising...)
  5. 8. a chemical process where oxygen is used to make energy from carbohydrates (sugars)
  6. 9. the rising levels of CO2 in the blood (acidosis), resulting is faster, deeper breathing- blows off more CO2 to restore back to normal blood pH
  7. 10. moving air into and out of the lungs (breathing)
  8. 11. poor oxygen transport to the tissues of the body
  9. 13. the air remaining in the lungs after expiration, allows gas exchange to go on (even between breaths)
  10. 16. every breath someone makes
  11. 17. labored breathing
  12. 18. a passive process that depends on natural lung elasicity, muscles relax,air is pushed out of the lungs
  13. 20. corresponds to the lung parenchyma and includes the respiratory bronchioles, alveolar ducts, and alveoli.
