module 14: the respiratory system

5. The ability of the lungs to stretch and expand.
6. The exchange of gases between the blood and body tissues (oxygen enters cells, carbon dioxide enters blood).
9. The exchange of gases between the alveoli and the blood in the lungs.
11. (Carbon Dioxide) A waste gas produced by cellular respiration and expelled through the lungs.
13. The connection point between two or more bones; also called a joint.
14. The amount of air inhaled or exhaled during a normal breath.
15. To inhale a foreign substance (food, liquid, vomit) into the airway or lungs.
17. The amount of air left in the lungs after a normal exhalation (expiratory reserve volume + residual volume).

1. The part of the respiratory system including the trachea, bronchi, bronchioles, and lungs.
2. The process by which cells use oxygen to break down glucose and produce ATP, releasing carbon dioxide and water.
3. The amount of air that remains in the lungs after a forceful exhalation; prevents lung collapse.
4. The part of the respiratory system including the nose, nasal cavity, pharynx, and larynx.
7. The process of moving air into and out of the lungs (breathing).
8. A collapsed lung caused by air entering the pleural space.
10. (Oxygen) A gas necessary for cellular respiration; used by cells to produce energy (ATP).
12. The maximum amount of air the lungs can hold after taking the deepest possible breath.
16. A slippery substance in the alveoli that reduces surface tension and prevents lung collapse.
