Spiracles open into large tracheal tubes. These, in turn, lead to ever-finer branches. The branches penetrate to every part of the body. Full article >>>
spiracles: a series of openings on the body surface of terrestrial arthropods that open into tiny air tubes that assist in gas exchange. spirilla: flexible spiral bacteria (singular, spirillum). spirochetes: rigid spiral bacteria. Full article >>>

They exchange gases through a tracheal system, with external openings called spiracles dividing into finely branched tubules that carry gases directly to metabolizing tissues. Full article >>>
spiracle -- In insects and some other terrestrial arthropods, a small opening through which air is taken into the tracheae. Insects have several spiracles, arranged along the sides of the abdomen. Full article >>>
