Tracheal respiration is a respiratory process found in insects and some other arthropods. It involves the use of a network of tubes called tracheae that extend throughout the body, delivering oxygen directly to tissues and removing carbon dioxide.
These tubes connect to small openings called spiracles on the body surface, allowing air to enter and exit.
Tracheal respiration is efficient for small organisms with a high surface-area-to-volume ratio. It supports the metabolic needs of insects, ensuring oxygen supply and waste removal without the reliance on circulatory systems found in vertebrates.
