Respiratory System

3. Extends from soft palate to epiglottis of larynx inferiorly
4. Posterior to epiglottis and extends to larynx; accomodates both ingested food and air
6. air first passes into the respiratory tract through these
7. serves only as an air passage; lies above the soft palate
9. last portion of the nonrespiratory conducting airway, which subdivides into respiratory bronchioles
14. Type of bronchioles that respirate the alveoli
16. place where air inhaled through nostrils is filtered and humidified
18. food passageway posterior to trachea
19. Flap-like, flexible elastic cartilage located superior to opening of larynx

1. Also known as the windpipe, air enters this structure from the larynx
2. The trachea breaks into two of these
5. arise after primary bronchi with each serving as airway to specific lobe of lung
8. dome-shaped, muscular partition separating the thorax from the abdomen
9. Made up of 50% cartilage and 50% smooth muscle
10. The biological system that introduces respiratory gases to the interior and performs gas exchange
11. Three pairs of lobelike structures that increase air turbulence
12. The beginning of the lower respiratory system
13. Ring-shaped and located inferior to thyroid cartilage
15. May also be referred to as a male's "Adam's Apple"
17. Balloonlike expansions that are made up of simple squamous epithelial cells
