BIOE 398BS: Quantitative Human Systems Physiology Spring 2008 Bioengineering, University of Illinois at Urbana-Champaign 1 Problem Set 6. Due Friday, February 29, 2008 at the beginning of class. 1. What factors determine: a. Total Lung Capacity? b. Residual Volume? 2. What is the volume of the anatomical dead space in respiration? What percentage of a total breath does this represent? Where does this “dead volume” air reside in the respiratory space at the end of expiration? Where does it reside at the end of inspiration? Assume that the breathing time, ie time for inspiration and expiration, is very short. 3. List the three fluids (besides blood) in the respiratory system and explain their function. 4. Define the equal pressure point in the respiratory system. What is the effect of a reduction in elastic recoil pressure on the location of the equal pressure point? In this

Unformatted text preview: same situation what would be the effect of increasing effort on the location of the equal pressure point? 5. Sketch both a spirogram and an expiratory flow-volume curve (See figure 28-9). Describe the experiment that is being performed and what is represented on the plots. Do both experiments measure inspiration and expiration? 6. What is the effect of changing lung volume (increasing and decreasing) on airway resistance? 7. Briefly describe the mechanical and functional (ie. how lung function is impacted) defect in the following lung diseases: (Hint: see chapter 28 descriptions, not Chapter 27s short mention). a. pneumothorax b. chronic bronchitis c. asthma d. emphysema e. COPD, chronic obstructive pulmonary disease...
