**[Respiration Group Activity 2 (1/29)]** 1. Carbon dioxide moves from the blood into alveoli at the lungs. List the four membranes that carbon dioxide must pass through as it goes from the blood into the alveoli. 2. Compare intrapulmonary and atmospheric pressure (which is higher, lower) during inspiration and expiration. Detail how this causes air to move (and in what direction). 3. List the two factors that determine airflow. Detail if each is directly proportional or indirectly proportional to flow. 4. State if each of the following increases or decreases pulmonary ventilation: a. Increased resistance b. Decreased resistance c. Increased alveolar surface tension d. Decreased alveolar surface tension e. Increase compliance f. Decreased compliance
