Question
Chapter 13, Problem 19SAE
Summary Introduction
To review:
The factors responsible for determining the direction of diffusion of carbon dioxide and oxygen in the lungs.
Introduction:
The movement of gases between lungs and body take place by the process of diffusion. Diffusion is a concentration-dependent phenomenon. Its direction for any gas is from a region of higher concentration to a region of lower concentration.
