-The surface that the gases cross is called the respiratory surface and the gases move across this surface by the process of diffusion. -Once transported they need to be transported to parts of the body that need them. -The gaseous exchange system allows exchange of carbon dioxide with external environment in plants and animals. -Transport system carries chemicals from where they enter the body to where they are used.
