INFLEXIBLE PLUMBING SYSTEM. “Unlike many other ectotherms, in insects, gas exchange takes place through a system of tubes, the tracheae, that lead directly to the cells of the mitochondria, where oxygen acts as an electron receptor during respiration. The exceptionally high power demands of insect flight, coupled with this gas exchange system, led early physiologists to conclude that large modern flying species may be at their performance limits.”
