Respiratory System | ENT 425 – General Entomology

Air enters the insect’s body through valve-like openings in the exoskeleton. These openings (called spiracles) are located laterally along the thorax and abdomen of most insects — usually one pair of spiracles per body segment. Air flow is regulated by small muscles that operate one or two flap-like valves within each spiracle — contracting to close the spiracle, or relaxing to open it.
