Insects have interesting respiratory systems where air enters through small external openings called spiracles, which lead to a dense mass of tubes called tracheae, which subdivide into smaller tubes, and at the end of each tracheae the thin, moist tracheole acts as the gas exchange surface. Tracheae are so confusingly named as they are also cartilaginous tubes like the human trachea and it's just the Latin plural of trachea, but it's referring to a different organ.
TLDR: insects have tracheae!
