WebBecause the exoskeleton is impermeable respiratory gases must move into the insect through a series of internal tubes called tracheae or tracheal tubes. These tracheae are highly branched helping to increase the Surface area : volume ratio available for gas exchange. Tracheoles WebThe tracheal system consists of a number of tubes that open to the exterior by paired respiratory pores (spiracles) and is similar to that of insects. Diffusion of gases occurs within small fluid-filled tubes that ramify over the internal organs. Scorpions, tailless whip scorpions, and whip scorpions rely upon book lungs.
