Question
Chapter 42, Problem 42.5CR
Summary Introduction
To explain: Why altitude does not affect an animal’s capacity to eliminate CO2 through gaseous exchange.
Concept introduction: The gaseous exchange in an animal is done on the basis of partial pressure, which is based on the particular gas exertion in a mixture of gas. The environment and the respiratory surface always strongly favor the release of carbon dioxide to the atmosphere. The net diffusion of a gas occurs from its region of higher to lower partial pressure.
