Across
  1. 5. amount of air that can be forcibly exhaled after tidal expiration
  2. 6. a passive process that depends on natural lung elasicity, muscles relax,air is pushed out of the lungs
  3. 8. amount of air that can be forcibly taken in over the tidal volume
  4. 11. gas exchange between blood and tissue cells in the systemic capillaries
  5. 13. the center of the larynx, (vocal chords)
  6. 17. the total amount of exchangeable air
  7. 19. every breath someone makes
  8. 21. gas exchange between pulmonary blood and alveoli, oxygen is loaded into the blood & CO2 is unloaded from the blood
  9. 22. a chemical process where oxygen is used to make energy from carbohydrates (sugars)
  10. 23. labored breathing
  11. 24. the air remaining in the lungs after expiration, allows gas exchange to go on (even between breaths)
Down
  1. 1. the absence of oxygen
  2. 2. 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.
  3. 3. a part of emphysema (a respirary disorder), discoloration due to poor circulation and inadequate oxygenation of the blood
  4. 4. increased respiratory rate, often due to extra oxygen needs (exercising...)
  5. 7. diaphragm and external intercostal muscles contract, size of thoracic cavity increases,air is sucked into the lungs
  6. 9. corresponds to the lung parenchyma and includes the respiratory bronchioles, alveolar ducts, and alveoli.
  7. 10. moving air into and out of the lungs (breathing)
  8. 12. the soft sounds of air filling alveoli
  9. 14. (a lipid molecule) coats gas-exposed alveolar surfaces
  10. 15. 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
  11. 16. poor oxygen transport to the tissues of the body
  12. 18. 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.
  13. 20. the area where gas exchanges between the alveoli and blood occurs in the lungs
