Answer: Insects have spiracles, which allow air to move into their tracheal system. Since insects don't have lungs, they use spiracles to exchange oxygen and carbon dioxide with the outside air. Insects open and close their spiracles through muscle contractions. Oxygen molecules then travel via the insect's tracheal system.
