BIO304L: Human Physiology Lab

Unit 9: Respiratory Physiology   This lab reviews the definitions of “tidal volume,” “inspiratory” and “expiratory” reserve volume, and “vital volume.” This unit also explains how to measure these volumes using a spirometer and presents various respiratory diseases and their effects on lung capacity.  

Unit 9 Time Advisory
This unit will take approximately 4 hours to complete.

    Instructions: Please review pages 66 through 68, to learn about the objectives of the ventilation experiment.  Then read pages 74 through 81 to learn about the tools and procedures involved in this analysis, and, lastly, fill out the worksheet based on the estimated data learned in the Web Media presented below.

    Instructions: Please watch the first video (about 5 minutes) to see images of a spirometer and learn about the process of spirometry.  The second video clip, “Lung Capactiy Spirogram” (about 2 minutes), reviews the volumes produced by the ventilation process.  Lastly, please click the third link and choose the “Respiratory” Module and work through the sections starting with “Spirometry” and ending with “Diseases”.  These pages are interactive; please check your estimated answers.  Through practice, you can observe how lung capacities change once conditions are changed.
