Question
Chapter 47, Problem 1IQ
Summary Introduction
To explain: That how does emphysema affect the diffusion of gases in and out of the lungs, based on Fick’s law.
Introduction: Gas exchange is the process by which gases move passively by the diffusion across a surface. Gases are constantly produced and consumed by

Students have asked these similar questions
How does idiopathic pulmonary fibrosis change the structure of the lungs, and how will this affect gas exchange?
Why must the lung be able to return to its normal non-deflated shape? and describe the factors which enable this to happen.
Indicate whether the changes in respiratory volumes or capacities described are observed A) during an acute asthma attack, B) in emphysema C) both during an acute asthma attack and in emphysema, or D) not during an acute asthma attack or in emphysema.
Note that the acute asthma attack is in a person not taking ventolin (ie no inhaler).
Decrease in total lung capacity
Increase in residual volume
Decrease in FEV1 (forced expiratory volume in one second)
Decrease in tidal volume
Decrease in expiratory reserve volume
