Chapter 13, Problem 7AAE

Summary Introduction

To determine Whether a person, whose alveolar membranes have become thickened enough to moderately decrease the rate of diffusion across it, have a lower arterial partial pressure of oxygen at rest and during exercise.

Introduction: The exchange of gases between the alveoli and the capillaries through the process of diffusion is affected by either due to decrease in the total surface area of alveoli or due to thickening of the alveolar membrane.
