Module  10.2 -Physiological Basics of The Respiratory System  

Module 10.2 Warm-Up

- Pick two(two you are most unfamiliar with) of the objectives from the unit objective list below and simplify the physiology that would explain each.

- Create a two-three sentence summary that could be used to explain the objective.  

- Use the notes (10.2), visible body (recommended), or any other resource that helps you understand best!

- Use the essential connections section if necessary (you you don't have space).

Essential Vocab: 

atmospheric pressure, intrapulmonary pressure, transpulmonary pressure, surface tension, respiratory volumes, tidal volumes, inspiratory reserve volume, expiratory reserve volume, respiratory capacities, functional residual capacity, total lung capacity, alveolar dead space, aveolar ventilation rate, partial pressure

Module Objectives: 

2. Mechanics of Breathing

            1.         Explain the functional importance of the partial vacuum that exists in the intrapleural space.

            2.         Relate Boyle’s law to the events of inspiration and expiration.

            3.         Explain the relative roles of the respiratory muscles and lung elasticity in producing the  volume changes that cause air to flow into and out of the lungs.

            4.       List several physical factors that influence pulmonary ventilation.

            5.       Explain and compare the various lung volumes and capacities.

            6.       Define dead space.

            7.       Indicate types of information that can be gained from pulmonary function tests.
