WebSep 15, 2004 · SUMMARY. Insects breathe through valved openings (spiracles) in their cuticle. Many insects open and close their spiracles in a cyclic pattern (discontinuous gas-exchange cycles, or DGC). These cycles were observed over half a century ago, their hypothesized function being to minimize loss of water from the tracheal system. … WebIt allows air to enter the insect and flow into the system of tracheae. There are rigid rings of cartilage that keep the tracheae open. A large number of tracheoles run between cells and into the muscle fibres - the site of gas exchange. For smaller insects, this system provides sufficient oxygen via diffusion.

WebMany insects exchange respiratory gases cyclically and discontinuously. A typical discontinuous gas exchange cycle (DGC) starts with a closed-spiracle (C) phase, during which little external gas exchange takes place, followed by a fluttering-spiracle (F) phase, which is usually dominated by diffusive oxygen uptake. The DGC is terminated by an …
