LUNG VOLUMES WORKSHEET 1. Use the diagram provided to answer the following questions. a. Identify the correct name of each lung volume labelled 1-6 and state the corresponding volumes in mL. b. What volume does the unmarked arrow represent? What is its value and significance? 2. Use the provided values to construct lung volume graphs on graph paper of lung volume (mL) vs time. Show multiple cycles of tidal breathing and at least 1 maximum exhalation and 1 maximum inhalation. Label all the different lung volumes using arrows and labels. It may help to first determine the missing lung volumes of each data set. a. RV = 1 L, ERV = 700 mL, TV = 500 mL, IRV = 2 L b. VC = 6500 mL, TV = 600 mL, IRV = 2900 mL, TLC = 7200 mL c. RV = 900 mL, VC = 4900 mL, IRV = 2300 mL, ERV = 2300 mL d. RV = 800 mL, IC = 3300 mL, VC = 5000 mL, TV = 400 mL 3. A student’s TV, IRV and ERV are measured. Is this enough information to determine the student’s total lung capacity? Explain why or why not. 4. Is it physically possible to measure a person’s total lung capacity? Explain why or why not.
