Textbook Question
Chapter 17, Problem 21RQ
The cartoon coyote is blowing up a balloon in another attempt to catch the roadrunner. He first breathes in as much air as he can, then blows out all he can into the balloon.
- a. The volume of air in the balloon is equal to the ________ of the coyote’s lungs. This volume can be measured directly by measuring the balloon volume or by adding which respiratory volumes together?
- b. In 10 years, when the coyote is still chasing the roadrunner, will he still be able to put as much air into the balloon in one breath? Explain.

During respiration, oxygen is inhaled through the airways into the alveoli where gas exchange occurs. For each condition described below, state if the flux of oxygen through the blood gas barrier into the pulmonary capillaries increases or decreases. Use Fick’s law to justify your answer.
a. Climbing to the top of Mt. Everest
b. More abundant but smaller alveoli
c. Extreme increase in pulmonary capillary pressure
d. Pulmonary fibrosis
To determine the possible obstruction of the airway, a FEV may be measured using a spirometer. Under normal circumstances, a healthy adult can expel 75% to 85% of the vital capacity in 1.0 second (FEV1). Predict how this would change in a person who has asthma and explain the reason why.
Which of the following is the definition of residual volume?
A. Volume of air remaining in the lungs after a maximal exhalation.
B. Maximal volume that can be exhaled from end-expiratory position.
C. Maximal volume expired after maximal inspiration.
D. Volume in the lungs at maximal inflation.

- Spirometry and lung volumes may be two PFTs that you have heard of. They help to diagnose obstructive or restrictive lung disease, monitor disease progression, and check whether treatments are effective. Understanding the different volumes and capacities associated with lung function will help you to better understand PFTs, respiratory disease and treatment for your patients. Lung volumes include tidal volume (TV), inspiratory reserve volume (IRV), expiratory reserve volume (ERV), and residual volume (RV). The various lung capacities include inspiratory capacity (IC), vital capacity (VC), functional residual capacity (FRC), and total lung capacity (TLC). choose 3 different lung volumes or lung capacities to explain in your own words. research a chronic lung disease (such as asthma, COPD, emphysema, fibrosis, etc) and explain how it affects specific lung volumes and/or capacities.arrow_forwardThe information provided suggests that: A. hemoglobin has more affinity to oxygen than to carbon monoxide.
