6. the process of breathing in. Oxygen is moved into the lungs during inhalation.
7. muscles in between the ribs and move to a limited degree, helping the lungs to expand and contract.
10. trachea divides into two main branches
11. sticky phlegm or liquid which catches and holds much of the dust, germs, and other unwanted material that has invaded the lungs
12. bones supporting and protecting the chest cavity
16. two membranes, actually one continuous one folded on itself, that surround each lobe of the lungs and separate the lungs from the
chest wall. The fluid between the two membranes helps the lungs glide easily against the chest wall during breathing.
18. flap of tissue that guards the entrance to the windpipe closing when anything is swallowed that should go into the esophagus and
stomach
Down
1. air sacs at the end of the bronchioles
2. collects incoming air from the nose and mouth and passes it downward to the windpipe (trachea)
3. the process of breathing out. Carbon dioxide is removed during exhalation.
4. like very small hairs that have a wave-like motion which line the bronchi
5. composed of 21% oxygen, 78% nitrogen and 1% various other gases
8. or windpipe is the passage leading from the throat (pharynx) to the lungs
9. the preferred entrance for outside air into the respiratory system. The hairs that line the wall are part of the air-cleaning system
10. smallest subdivision of the bronchi
13. the strong wall of muscle that separates the chest cavity from the abdominal cavity. By moving downward, it creates suction in the
chest to draw in air and expand the lungs.
14. blood vessels that surround the walls of the alveoli. This is where carbon dioxide and oxygen are exchanged by diffusion
15. another entrance for outside air, especially in people whose nasal passages may be temporarily obstructed, as by a cold or during
heavy exercise
17. Respiration is the process when oxygen has diffused in to the bloodstream and the oxygen and nutrients combine to release the
energy needed for life activities. The waste products of cellular respiration are carbon dioxide and water
19. contains the vocal chords where moving air being breathed in and out creates voice sounds
