THE RESPIRATORY SYSTEM
Across
- 1. lungs expand through contraction which increases lung volume
- 4. no muscle contraction are involved process
- 5. lung collapse is prevented by adhesion of the membranes
- 8. two phases of breathing: expiration
- 9. expansion of the lungs is helped by between pleurae
- 10. exchanging gases between the blood and the body cells
- 12. when the inspiratory muscles,the diaphragm and external intercostals
- 13. breathing or pulmonary ventilation is a process
- 21. process of moving air into and out of the lungs
- 22. lung collapse due to alveoli collapse
- 23. when inspiratory muscles contract,intra-pulmonary volume
- 24. pressure inside the lung is pressure
- 25. the lungs adhere tightly to the walls
- 28. movement of air out of the lung
- 30. if the intrapleural pressure becomes equal to the atmospheric pressure the lungs immediately
Down
- 2. gases passively flow out to the pressure
- 3. using the oxygen in cell processes and the production of carbon dioxide
- 6. movement of air into the lung
- 7. alveolar pressure> pressure during expiration
- 11. exchanging gases between the air in the lungs and the blood
- 14. during inhalation lungs fill with
- 15. is reversed by drawing air out of the intrapleural space
- 16. ease with which the lungs and thoracic wall can be expended
- 17. intrapleural pressure is always
- 18. gas travels from pressure to low pressure areas
- 19. pressure between the pleurae is pressure
- 20. pressure changes that drive inhalation and exhalation are governed,in part,by law
- 26. gas transport by
- 27. At the end of a normal expiration the chest is the rib cage is descended
- 29. and by the presence of surfactant in
