Chapter 4, Problem 1CAQ2
Summary Introduction
To review:
The given blank space in the statement, “Because gas diffusion is indirectly related to the thickness, the diffusion of the oxygen across the alveolar-capillary membrane in this case________.”
Introduction:
In the given case, the patient is suffering from pulmonary edema that affected the thickness of the capillaries of the patient. The diffusion of gases in the human body takes place in the alveolar-capillary system. The increase in the thickness also affects this diffusion of oxygen and carbon dioxide.
Please refer to Clinical Application Case-1 for further information.
