Irvine, Calif., Feb. 14, 2005 -- A new study investigating the respiratory system of insects may have solved a mystery that has intrigued physiologists for decades: why insects routinely stop ...

The insect respiratory system is designed to accommodate occasions when the insect is active. For example, a grasshopper is most active when it flies.

The basis of this gigantism is thought to lie in the insect respiratory system. In contrast to vertebrates, where blood transports oxygen from the lung to the cell, ...

Argonne National Laboratory researchers have confirmed the hypothesis that the basis of such gigantism is the insect respiratory system. In contrast to vertebrates, where blood transports oxygen ...

Also bizarre: Insect respiratory systems are not patched into the animals' circulatory systems, as they are in humans, where the lungs exchange gases with the bloodstream.

Together, they will study the role of hydrodynamic slip -- an unusual behavior of fluids in special conditions -- in insects' respiratory systems, looking at oxygen delivery at the micro level.

Mammals, birds, and reptiles all respire through a combined respiratory and circulatory system, ... These respiratory differences make insects highly efficient at using the oxygen they take in.

The respiratory systems of animals must guarantee an efficient oxygen supply. But it seems that, in some insects, they have evolved to restrict the flow of oxygen too.

That means many of an insect’s body systems are like yours. But there are three body systems that are super different for insects. Those are the skeletal, circulatory and respiratory systems.

Insects can also adjust the amount of air they let into their respiratory system. The insect’s tracheae system is much more efficient at reducing water loss when you compare it to the pill bug ...
