The following information comes from a book called "The biology of the honey bee" by Mark L. Winston. p. 34. "Bees have no lungs for breathing; rather they use a system of tubes which carry oxygen to and carbon dioxide away from cells. This system of breathing tubes, or tracheae, is connected to the outside world by a series of holes in the cuticle called spiracles. When the bee is inactive gas exchange can operate simply by diffusion, but during periods of increased activity bees pump their abdomens to increase gas exchange, using expanded sacs of the trachea as bellows (Bailey, 1954).
