Insects exchange gases through air-filled tubes called trachea, which branch into thin, permeable tracheoles, with air entering via pores called spiracles.
Os insetos trocam gases através de tubos cheios de ar chamados traqueias, que se ramificam em traquéolas finas e permeáveis, permitindo a entrada de ar através de poros chamados espiráculos.
