• Instead of lungs, insects breathe with a network of tiny tubes called tracheae. Air enters the tubes through a row of holes along an insect's abdomen. The air then diffuses down the blind-ended tracheae.
• Since the biggest bugs have the longest tracheae, they should need the most oxygen to be able to breathe. Air enters the respiratory systems of insects through a series of external openings called spiracles.
• These external openings, which act as muscular valves in some insects, lead to the internal respiratory system, a densely networked array of tubes called tracheae. The respiratory system consists of air-filled tubes or tracheae, which open at the surface of the thorax and abdomen through paired spiracles.
• The muscular valves of the spiracles, closed most of the time, open only to allow the uptake of oxygen and the escape of carbon dioxide.
