The Respiratory System
Across
- 2. Total amount of air that can be inhaled and then exhaled with maximum effort
- 3. Substance secreted by great alveolar cells that prevents alveoli from collapsing during exhalation
- 5. Respiratory group that sets the respiratory rhythm at 12 breaths per minute
- 6. Barrier between the alveolar air and blood
- 7. Air remaining in lungs after maximum expiration
- 9. Increase in the diameter of a bronchus or bronchiole caused by the release of epinenphrine
- 11. A deficiency of oxygen in a tissue or the inability to use oxygen
- 12. Portion of the pharynx that only passes air
- 14. Disorders that interfere with airflow by narrowing or blocking the airway
- 17. The process of carrying gases from the alveoli to the systemic tissues and vice versa
- 19. Muscle that is the prime mover of respiration
- 21. The ease with which the lungs can expand
- 26. Flap of tissue that guards the superior opening of the larynx
- 29. Type of epithelium in nasal cavity that detects odors
- 30. Collapse of all or part of a lung
- 31. Type of sensory receptor that responds to smoke, dust, pollen, and cold air
- 32. Type of breathing that is relaxed, unconscious, and automatic
- 33. Pressure that exists within the lungs
Down
- 1. Type of chemoreceptor that responds to changes in pH of CSF
- 2. Serous membrane that covers lungs
- 4. Final branches of the conducting system
- 8. Pressure that exists between the two pleural layers
- 9. Name for the segment of functionally independent lung tissue ventilated by segmental bronchi
- 10. Portion of the bronchial tree that participates in gas exchange
- 13. Type of lung cancer that originates in mucous glands of lamina propria
- 15. Device that recaptures expired air and records different variables
- 16. Law that the given volume of a gas is directly proportional to its temperature
- 18. Branching system of air tubes in each lung
- 19. Hemoglobin with no oxygen
- 20. Slit through which the lung receives main bronchus, blood vessels, lymphatics, and nerves
- 21. The separate contribution of each gas in a mixture
- 22. The exchange of bicarbonate ion and chlorine ion during systemic gas exchange
- 23. Nerve that supplies the diaphragm
- 24. internal median ridge in lowermost tracheal cartilage that directs airflow in the right and left bronchi
- 25. Muscle found on posterior side of trachea that allows esophagus to expand when food is swallowed
- 27. Right and left halves of the nasal cavity
- 28. Condition in which the alveolar walls break down and the lungs are fibrotic and less elastic
