Q 1. Despicable as his character was, it was hard not to applaud as Deakins (played by John Travolta) shutPritchett up. Specifically, which part of Pritchett's respiratory tract did he crush? 2. 2. It seems odd that Pritchett was still able to exhale, but he couldn't inhale. a. When we exhale, does the air push against the walls of the respiratory conducting division or pull in?Is exhalation an active or a passive process? b. Which tissue normally prevents the trachea and bronchial trees from collapsing under the negativepressure of inhalation? c. Why don't bronchioles need this support? d. Which muscles are responsible for controlling inhalation? 3. 3. The conducting structures are protected from collapsing during inhalation, but the alveoli are at riskof collapsing at the end of exhalation, even in the dry desert. Explain the force that could cause the wetsurfaces of the alveoli to stick together, especially at the end of a long vocal outburst, like yelling orcrying. 4. 4. Even though he was whining like a baby, Pritchett was an adult and didn't have to worry about hisalveoli collapsing. a. Which lipoprotein prevents our alveoli from collapsing? b. Which alveolar cells produce it? c. Which newborn babies might be at risk of alveolar collapse because they do not yet produce thislipoprotein? 5. 5. Pritchett's crushed airway may have been a dramatic device in the film, but restricted airways are a very real concern for people who suffer from asthma. This threat is so serious that Deakins and Hale would have been disqualified from Air Force flight training if they had asthma. a. One trigger for an asthma attack is irritation of the respiratory tract. Which sorts of airborne particles might cause irritation? b. Draw a cross section of a bronchiole and describe how inflammation of the irritated airway would restrict airflow. c. Asthma attacks can also involve muscle spasm. Redraw your cross section of the bronchiole and explain how smooth muscle spasm would restrict airflow. d. Which medications are commonly used to treat asthma? How do these medications aid the person to breathe easier? Take pictures of your drawings, click on Brows your computer and attach all your drawings.
