Flies breathe through a complicated structure of tubes (called tracheae and tracheoles) and air sacs. Oxygen is pulled into the body through openings in their abdomens called spiracles. Once the oxygen has been pulled in, the outer most vents close and the air is forced into increasingly smaller pipes known as tubules, until it reaches the required cells.
