of this document, click Duplicate. Short Answer Questions: 1. Describe the relationship between intrapulmonary pressure, atmospheric pressure, and air flow during normal inspiration and expiration, referring to Boyle's law. 2. Resistance varies in Mike's conducting airways. Using your understanding of respiratory anatomy, explain where in his airway the resistance is highest and why. 3. Several physical factors that influence the efficiency of pulmonary ventilation are compliance, alveolar surface tension, and airway resistance. Briefly describe each factor and identify the one that is affecting Mike's efficiency of breathing. 4. What must happen to Mike's intrapulmonary pressure in order for him to maintain normal air flow during inhalation and exhalation when he is having one of his asthma attacks? 5. Albuterol is a selective beta-2 adrenergic agonist, which means it specifically activates beta-2 adrenergic receptors on smooth muscle in the airways. How does this improve Mike's asthma?

A car is moving along a straight road. At time t seconds, the position of the car (in feet) is s(t) = 2t². Find the average velocity of the car over the time intervals given below. (a) t = 11 to t = 11.3 seconds (b) t=11 to t = 11.03 seconds (c) t = 11 to t = 11.003 seconds (a) The average velocity of the car over the time interval from t = 11 to t = 11.3 seconds moving along a straight road is \frac{feet}{sec} (Simplify your answer. Round to one decimal place as needed.)
