"Roaches and other insects breathe through spiracles [surface openings] in the bodies instead of lungs, so the blood doesn’t need to carry oxygen from one place to another," Moore said. Similarly, the spiracle openings allow air into the interior tracheal system bathing the insect's tissues with oxygen. Wiley-Blackwell, 2004, Merritt, Richard W. and Cummins, Kenneth W.
