Insects like cockroaches and houseflies respire through a tracheal system, a network of tubes that permeate their bodies. Air enters through spiracles, tiny pores on body segments, leading to tracheal chambers. The trachea branches reach every cell, delivering oxygen directly. Abdominal movements facilitate air intake and expulsion, with expansion drawing air in and contraction pushing it out through the spiracles.
