Across
  1. 3. Pressure exerted into the pleural cavity
  2. 5. Relaxation of smooth muscles in the airway, increased
  3. 8. Balloon shaped sac that facilitates gas exchange
  4. 11. High levels of carbon dioxide in your blood
  5. 12. Pressure exerted into the alveolar cavity
  6. 13. Decreased ventilation, increased CO2
  7. 14. Chronic condition where airways are constricted by triggers such as allergens, irritants, or infections
  8. 19. In ______ capillaries, alveoli walls supply the blood with oxygen and collects carbon dioxide to perform a gas exchange
  9. 20. Increased ventilation, decreased CO2
  10. 22. Brief interruption in breathing that resumes spontaneously
  11. 23. Low levels of oxygen in your blood
  12. 24. Also known as the chest, a cavity that holds major organs such as the heart and lungs
  13. 25. The _______ effect describes how CO2 is affected by oxygen concentrations
Down
  1. 1. The _____ effect describes the inverse relationship between CO2 and oxygen
  2. 2. Increased breathing rate as a result of exercise
  3. 4. Irreversible chronic condition where alveolar walls are broken down due to damaged lung tissue as a result of excessive trypsin release
  4. 6. What type of hemoglobin is not attached to oxygen?
  5. 7. The feeling of not being able to get enough air into your lungs
  6. 9. What medical device is used to measure the volume of air breathed in and out?
  7. 10. Airway constriction due to smooth muscle tightening which causes airways to narrow
  8. 15. Abnormal breathing pattern, sometimes due to brain injury
  9. 16. Thin dome-shaped muscle at the base of the chest
  10. 17. Law in which a corresponding change of pressure and volume are constant as long as the temperature remains constant
  11. 18. Tiny branches that deliver air to small sacs in the lung
  12. 21. Air leaking outside of the lung within the chest wall, causing pressure against one’s lungs
