Across
- 3. bleeding from the nasal mucosa: aka nosebleed
- 4. pons center that sends inhibitory signals to prevent over inflation of the lungs & ensure normal rhythmic breathing
- 5. forms as carbon dioxide binds with the amino acids of the hemoglobin molecule
- 8. nonrespiratory procedure intended to clear the nasal passages of an irritant; most often followed by "Bless you"
- 9. term for tertiary bronchial divisions found at the end of the right & left bronchus which communicate with each lobe of the lung
- 11. blood vessels that supply blood to & from the lung tissue itself
- 14. comical problem that results when the diaphragm spasms involuntarily
- 16. brainstem region that houses the rhythmicity area that coordinates the basic rhythm of the respiratory cycle
- 18. organelle that uses the oxygen you inspire as part of the cell respiration process
- 19. type of sinus found surrounding the nasal cavity, serves as a resonating chamber, lightens the skull, & produces mucus
- 22. inflammation of the nasal mucosa characterized by congestion & post-nasal drip
- 23. highly contagious disease caused by a bacillus infection
- 24. mechanical device used to measure lung volumes & capacities
- 25. auditory tube that opens in the nasopharynx; when opened, serves to equalize pressure in the middle ear
- 27. prominent laryngeal cartilage piece that forms a protruding ridge in the midline, in males, called the Adam's apple
- 28. any state in which an inadequate amount of oxygen is available to tissues
- 29. pleura layer found covering the external surface of the lungs
- 30. as bicarbonate ions travel through the blood plasma, it serves as an important ? to blood pH
- 31. white blood cell found wandering the terminal bronchioles & alveoli; aka dust cell
- 33. respiratory & digestive structure that extends from the back of the nasal cavity to the top of the larynx
- 34. cartilaginous flap found attached at the top of the larynx; functions to channel food into the esophagus & not into the larynx
- 36. the enzyme carbonic ? catalyzes teh conversion of carbon dioxide & water into carbonic acid
- 37. passive process where muscle relaxation & lung recoil pushes air out of the lungs; aka exhalation
Down
- 1. inhalation of gases using the diaphragm & external intercostals; aka inhalation
- 2. compound formed as oxygen combines with its carrier protein
- 6. name for the epithelial layer running from the nasal cavity to the bronchi; one layer that appears multilayered
- 7. obstructive lung disorder where smooth muscle in teh bronchioles spasm & mucus builds up
- 10. sheet of muscle that separates the abdomen from the thorax; contracts to create an area of low pressure in the lungs
- 12. escalator found in the trachea which functions to move debris-laden mucus to the top of the larynx
- 13. mechanical process of filling & emptying the lungs of air; aka breathing
- 15. flat bone that fails to unite with its pair leading to cleft palate
- 17. one of the 3 projections found in the nasal cavity; highly vascular & actively producing mucus
- 20. type of breathing characterized by animals possessing a diaphragm; opposite of positive
- 21. a sac-like respiratory structure found at the ends of the bronchioles; lined with simple squamous epithelium so diffusion of gases can occur
- 24. phospholipid secreted by cuboidal cells in the alveoli that functions to reduce surface tension
- 26. carbon dioxide forms these ions as carbonic acid dissociates in the blood plasma
- 32. most common lethal genetic disease where viscous mucus clogs respiratory & digestive pathways; cystic ?.
- 35. neuron type located superior in the nasal cavity where they sense molecules in the inspired air
