Across
  1. 4. rigid tube or windpipe. Air enters from the larynx and travels down to midchest.
  2. 8. structures all the respiratory passages that serve as conduits to and from the respiratory zone (area of gas exchange).
  3. 9. when air enters the lungs from the outside
  4. 10. contains a right and left side formed by the division of the trachea, each plunges into the medial depression of the lung on its own side..
  5. 11. mucosa-covered projections or lobes in the nasal cavity, which increase the surface area of the mucosa that is exposed to air.
  6. 14. includes the respiratory bronchioles, alveolar ducts, alveolar sacs, and alveoli is the only site of gas exchange in the lungs.
  7. 15. a procedure in which the air in a person's own lungs is used to pop out or expel an obstructing piece of food.
  8. 22. midline divider of the nose.
  9. 23. a muscle that separates the thoracic cavity from the abdominopelvic cavity. One of the inspiratory muscles. The other is the external intercostals. When they contract it opens the thoracic cavity and draws air into the lungs.
  10. 24. two large organs that occupy nearly the entire thoracic cavity. The area of gas exchange between the respiratory system and the cardiovascular system.
  11. 25. the broad lung area that rests on the diaphragm.
  12. 26. pleural membrane that lines the walls of the thoracic cavity. Produces pleural fluid
  13. 28. superior portion of the pharynx. First part of the pharynx that air enters.
  14. 30. any of the many tiny air sacs of the lungs which allow for rapid gaseous exchange.
  15. 31. a slit-like passageway between the vocal folds
  16. 33. the narrow superior portion of each lung, located just deep to the clavicle.
  17. 37. cluster of lymphatic tissue located in the oropharynx (mid pharynx) at the end of the soft palate.
  18. 39. oxygen is transported through the bloodstream to the tissues where it is unloaded, and carbon dioxide diffuses out of the blood and into the alveoli to be expelled from the body.
  19. 42. ducts that drain tears from the eyes
  20. 43. the nostrils
  21. 44. breathing. Keeps gases in the air sacs of the lungs continuously changed and refreshed.
  22. 45. the Adam’s apple. Shield shaped, helps form the larynx
Down
  1. 1. c-shaped rings of cartilage that make the trachea rigid and allow esophagus expansion when we swallow a large piece of food, yet supports the trachea and keeps it open (patent).
  2. 2. smallest branches (conducting passageways) of the primary bronchi inside the lungs
  3. 3. the pair of posterior openings of the nasal cavity into the (naso)pharynx, above the palate of the mouth; a part of the passageway for air required in respiration.
  4. 5. organ system that carries out gas exchange. It includes the nose, pharynx, larynx, trachea, bronchi, and lungs.
  5. 6. voice box. Routes air and food into the proper channels and plays a role in speech.
  6. 7. inflammation of the nasal mucosa
  7. 12. visceral serous membrane covering the surface area of each lung.
  8. 13. respiration gas exchanges between the blood and cells inside the body
  9. 16. the formal term for gas exchange. It describes both the bulk flow of air into and out of the lungs and the transfer of oxygen and carbon dioxide into the bloodstream through diffusion.
  10. 17. slippery serous fluid that allows the lungs to glide easily over the thorax wall during breathing
  11. 18. cavity within the thoracic cavity that houses the heart.
  12. 19. protects the superior portion of the airways. The “guardian of the airways.”
  13. 20. separates the nasal cavity from the oral cavity. It is hard anteriorly and soft posteriorly.
  14. 21. a muscular passageway for food and air. (the throat)
  15. 27. part of the digestive tract. Tube in throat that abuts the trachea. Expands when we swallow
  16. 29. a ring of mucous-membrane lined, air-filled cavities located in the frontal, sphenoid, ethmoid, and maxillary bones. These cavities lighten the skull, produce mucus, and act as resonance chambers for speech
  17. 32. cluster of lymphatic tissue located at the base of the tongue.
  18. 34. when air leaves the lungs to the outside.
  19. 35. membrane the membrane separating air within the alveoli from the blood within pulmonary capillaries. It consists of the alveolar wall, the capillary wall, and their basement membranes. The respiratory membrane is very thin (less than 0.5 mm)
  20. 36. also called pleural cavity. More of a potential space than an active one, this cavity exists between the lungs and underneath the chest wall.
  21. 38. surgical opening of the trachea, done to provide an alternate route for air to reach the lungs.
  22. 40. cluster of lymphatic tissue found in the pharynx in the high nasopharynx region. Also called adenoids.
  23. 41. true vocal chords a pair of mucous membrane folds which vibrate with expelled air allowing for speech.
