7. 1. (B)Bronchioles – Smallest respiratory passageway 2
1. (B)Bronchioles – Smallest respiratory passageway 2. (G)Palate – Separates the oral and nasal cavities 3. (I)Phrenic Nerve – Major nerve stimulating the diaphragm 4. (E)Esophogus – Food passageway posterior to the trachea 5. (D)Epiglottis – Closes off the larynx during swallowing 6.(K)Trachea - windpipe 7.(A)Alveoli – actual site of gas exchange 8.(H)Parietal Pleura – Pleural layer covering the thorax walls 9.(L) Vagus Nerve – Autonomic Nervous System nerve serving the thorax 10. (F) Glottis – Opening between vocal folds 11. (C) Conchae – Fleshy lobes in the nasal cavity that increase its surface area 12. (O) Vocal Folds – Closes the glottis during the Valsava maneuver 13. (N) Uvula – Closes the nasopharynx during swallowing 14. (K) Trachea – The cilia of its mucosa beat upward toward the larynx
