Gas exchange adaptations
WebPhysiological features to tolerate water loss include adaptations such as: deployment of desiccation-resistant egg cases for embryonic development, reduction of the exposed surface areas across which water loss takes place (thus accepting reduced gas exchange and concomitant anaerobic respiration with accumulation of metabolic end products ... WebFor gas exchange systems to be efficient, they must have the 4 characteristics that maximise the rate of diffusion. The specialised respiratory surface must have a large surface area to volume ratio (SA : V). The specialised respiratory surface must be moist. The the specialised respiratory surface must be thin.
