WebInsects breathe using one or a combination of three gas exchange patterns; continuous, cyclic and discontinuous, which vary in their rates of exchange of oxygen, carbon dioxide and water. In general, there is a trade-off between lowering gas exchange using discontinuous exchange that limits water loss at the cost of lower metabolic rate. WebDec 1, 2005 · Discontinuous gas exchange cycles are one of the most striking gas exchange patterns shown by resting or quiescent insects. They were originally described in lepidopteran pupae (by Heller,1930; cf. Buck,1962) and the adults of several species ( Punt et al., 1957; Wilkins, 1960 ).

Air enters the respiratory systems of insects through a series of external openings called spiracles. These external openings, which act as muscular valves in some insects, lead to the internal respiratory system, a densely networked array of tubes called tracheae.

WebJan 1, 2009 · Mechanisms of Gas Exchange. Insect gas exchange occurs in a series of steps. Oxygen molecules first enter the insect via the spiracle, then proceed down the branching tracheae to the tracheoles. The terminal tips of the tracheoles are sometimes fluid-filled, so at this point gas transport may occur in a liquid medium rather than air. WebGas exchange by direct diffusion across surface membranes is efficient for organisms less than 1 mm in diameter.

The aquatic larval stage is the tadpole. Most amphibians must live in a moist environment. The skin and lungs are used for gas exchange in the adults while the larvae breathe with gills. Most amphibians produce toxins in the skin. Amphibians do not have scales, feathers or hair. methane gas purifier

"WebThese veins provides support and a way for nutrient transport and gas exchange to occur within the wing. Scientists often use wing venation to identify insects because different groups of insects have distinct venation patterns. Early winged insects, like those in the Paleoptera, generally have wings with many cross veins. " - Gas exchange use by insects
