Bees, like other insects, do not have lungs. They have developed their own system of respiration called the tracheal system. This is made up of a number of openings which lead into tubes. The tubes divide and divide until they are very numerous and very small and spreading throughout the body carrying air to every cell in the insect's body. The openings are called spiracles, the larger tubes are tracheae, and the smaller tubes are tracheoles.
Look carefully at a bee and you may see a rhythmic movement of the abdomen. These are respiratory movements, and help exchange stale and fresh air in the trachaea.
