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. WebThe tracheae connect to the outside environment through openings in the insect body wall called spiracles. Spiracles are generally found laterally along an insect's thorax and abdomen. They can have filters or valves that open only when gas exchange is taking place.
