Diversity of respiratory structures in the animal kingdom. The area where gaseous exchange takes place with the environment is called the respiratory surface. Gaseous exchange takes place in all organisms by the physical process of diffusion. So the respiratory surfaces must have the following properties. It must be permeable to respiratory gases such as oxygen […]
