Question
Chapter 22, Problem 6TYK
Summary Introduction
Introduction:
The portion of body of the animal where the gas exchange occurs with the environment is known as a respiratory surface. The respiratory surface has to be moist for proper diffusion, should large enough to intake sufficient oxygen and thin layered for faster gas exchange.
