<span>Oxygen travels to insect tissues through tiny openings in the body walls called spiracles, and then through tiny blind-ended, air-filled tubes called tracheae. Therefore, insects obtain oxygen through the spracles, which are small abdominal holes that lead into traecheal tubes called tracheae that branch into smaller tubes called tracheoles.
