Alveoli Bronchi Larynx Trachea Rings of cartilage line much of the respiratory tract. In which of one the following would cartilage NOT be found? Question 3 3 / 3 pts Label the following five items from the diagram: Question 4 10 / 10 pts Trachea Nasopharynx Correctt! Oropharynx Alveoli 8/17/22, 8:43 PM 3/16 Label ALabel CLabel ELabel FLabel HYour Answer: A - nasal cavity C - soft palate E - glotties F - trachea H - tongue 8/17/22, 8:43 PM 4/16 The trachea is closed by the epiglottis. The epiglottis moves inferiorly, covering the trachea. This is to prevent food or liquid from entering the lungs. Your Answer: the trachea is closed by the epiglottis to prevent food from entering the lungs Explain what happens to the epiglottis during swallowing. Why? Note: Essay answers must clearly be in your own words. Question 5 5 / 5 pts Note: Essay answers must clearly be in your own words. Explain at least two differences between Type I and Type II alveolar cells. Question 6 5 / 5 pts Label A- Nasal Cavity Label C- Soft Palate/ Uvula Label E- Glottis Label F- Trachea Label H- Tongue 8/17/22, 8:43 PM 5/16 Correctt! (Negative pressure) False True True/False: Positive pressure is used to move air into the lungs. Question 7 2 / 2 pts Question 8 2 / 2 pts Your Answer: Type 1 thin simple squamous epithelium make up 95% of all alveolar cells Type 2 can divide to replace type 1 cells make up 5% of all alveolar cells a. Type I form the very thin simple squamous epithelium of the alveoli in junction with capillaries. Make up roughly 95% of alveolar epithelial cells. b. Type II produce and secrete pulmonary surfactant which is needed throughout the alveolar surface to keep the alveoli open. In addition, Type II cells can divide to replace damaged Type I cells. Make up roughly 5% of alveolar epithelial cells. 8/17/22, 8:43 PM 6/16 Correctt! (rib cage is lifted upward during inhalation) False True True/False: During inhalation the rib cage is lowered pull the lungs open. Question 9 2 / 2 pts Correctt! False
