    A good respiratory surface should be moist inorder for  respiratory gases to dissolve in it 

    It should be highly vascularised so that the respiratory gases should be distributed all round the body

    It should have a thin membrane to reduce the  diffusion distance . This is because  rate of diffusion is invesely propôrtional to distance

      It should possess a large surface area so that sufficient amount of gases can be exchanged
