Is the tracheal method of respiration found in insects?
In terrestrial insects, the respiration is tracheal and gases flow inside small tubes that connect the animal external surface and ramify to tissues and cells without the participation of blood. In arachnids, besides the tracheal respiration, book lungs (thin folds resembling leaves in a book) may also exist. ChaCha again soon!
