Across
- 5. the delicate serous membrane that covers the surface of each lung and dips into the fissures between the lobes.
- 11. each of a pair of serous membranes lining the thorax and enveloping the lungs.
- 12. the drawing in of breath; inhalation.
- 13. the outer membrane which is attached to the inner surface of the thoracic cavity.
- 18. both food and air pass. It can be found between the hyoid bone and the larynx and esophagus
- 20. The amount of air which enters the lungs during normal inhalation at rest.
- 21. firm, whitish, flexible connective tissue found in various forms in the larynx and respiratory tract.
- 22. the part of the larynx consisting of the vocal cords and the slitlike opening between them. It affects voice modulation through expansion or contraction.
- 24. a substance that tends to reduce the surface tension of a liquid in which it is dissolved.
- 25. a flap of cartilage at the root of the tongue, which is depressed during swallowing to cover the opening of the windpipe.

- 1. an infectious bacterial disease characterized by the growth of nodules (tubercles) in the tissues, especially the lungs.
- 2. a dome-shaped, muscular partition separating the thorax from the abdomen in mammals.
- 3. any of the many tiny air sacs of the lungs which allow for rapid gaseous exchange.
- 4. the ring-shaped cartilage of the larynx.
- 6. exhalation of breath.
- 7. the upper part of the pharynx, connecting with the nasal cavity above the soft palate.
- 8. the action of breathing.
- 9. the volume of air still remaining in the lungs after the most forcible expiration possible.
- 10. the part of the pharynx that lies between the soft palate and the hyoid bone.
- 14. a condition in which the air sacs of the lungs are damaged and enlarged, causing breathlessness.
- 15. any of the minute branches into which a bronchus divides.
- 16. the membrane-lined cavity behind the nose and mouth, connecting them to the esophagus.
- 17. inflammation of the mucous membrane in the bronchial tubes. It typically causes bronchospasm and coughing.
- 19. Cords folds of membranous tissue that project inward from the sides of the larynx to form a slit across the glottis in the throat, and whose edges vibrate in the airstream to produce the voice.
- 20. each of three thin curved shelves of bone in the sides of the nasal cavity in humans and other warm-blooded vertebrates, covered in mucous membrane.
- 23. a large cartilage of the larynx, a projection of which forms the Adam's apple in humans.
- 26. the hollow muscular organ forming an air passage to the lungs and holding the vocal cords;the voice box.
