Across
- 3. Process including normal exhalation; no muscular contraction is required
- 4. The bronchial tree begins at the trachea and ends at theses set of brochioles
- 6. Consisted of two or more alveoli that share a common opening
- 9. Simple squamous epithelium are the cells that make up the wall of the
- 11. Exchange of O2 and CO2 happen across this membrane;alveolar and capillary walls
- 12. The deepest layer of serous membrane that covers the lungs
- 13. First step of inhalation does this to the diaphragm and external intercostals
- 15. Diversion of pulmonary blood from poorly ventilated areas of lung, blood vessels response
- 18. These intercostals are only used during forced exhalation;depletion of the body's ATP
- 19. lowers alveolar surface tension
Down
- 1. Refers to how much effort is required to stretch the lungs and chest wall
- 2. When the alveolar pressure is this then atmospheric pressure, air moves into the lungs
- 5. Process of respiration in which pulmonary capillary blood gains O2 and loses CO2
- 7. Signals from this division of the autonomic nervous system cause bronchiodialation and decreased resistance
- 8. Set of nerves responsible for innervating the diaphragm and causing 75% of the body's air to enter the lungs
- 9. The collapse of part of a lung, or rarely, the entire lung
- 10. Double layered membrane that surrounds and protects each lung is called
- 14. The right lung has this fissure but the left lung does not
- 16. A breathing disorder in preemies in which the alveoli do not remain open due to a lack of surfactant
- 17. Larger diameter airways have this resistance
- 20. Exhalation starts when the external intercostals do this
