The invertebratetrachea refers to the open respiratory system composed of spiracles , tracheae, and tracheole s that terrestrial animal terrestrial arthropod s have to transport metabolism metabolic gas es to and from tissues. The distribution of spiracles can vary greatly among the many order biology orders of insect s, but in general each segment of the body can have no more than one pair of spiracles, each of which connects to an atrium and has a relatively large tracheal tube behind it. The tracheae are invaginations of the cuticular exoskeleton that branch anastomosis anastomose throughout the body with diameters from only a few micrometres up to 0.8 mm. The smallest tubes, tracheoles, penetrate cells and serve as sites of diffusion for water , oxygen , and carbon dioxide . Gas may be conducted through the respiratory system by means of active Ventilation physiology ventilation or passive diffusion . Unlike vertebrates , insects do not generally carry oxygen in their hemolymph haemolymph . This is one of the factors that may limit their size. A tracheal tube may contain ridge like circumferential rings of taenidia in various geometry geometries such as loops or helix helices . In the head , thorax , or abdomen , tracheae may also be connected to air sacs. Many insects, such as grasshopper s and bee s, which actively pump the air sacs in their abdomen, are able to control the flow of air through their body. In some aquatic insects, the tracheae exchange gas through the body wall directly, in the form of a gill . Note that despite being internal, the tracheae of arthropods are shed during moulting ecdysis .

Unreferenced date September 2008 Invertebrate zoology is the biology biological academic discipline discipline that consists of the study of invertebrate animals, i.e. animals without a vertebral column backbone a structure which is found only in fish , amphibian s, reptile s, bird s and mammal s. Invertebrates are a vast and very diverse group of animals that includes sponges , echinoderm s, tunicate s, numerous different phylum phyla of worms, mollusc s, arthropod s and many additional phyla. Single celled organisms or protist s are usually not included within the same group as invertebrates. Invertebrates are 97 of all named animal species , and because of that fact, this subdivision of zoology has many further subdivisions, including but not limited to Arthropodology the study of arthropods , which includes Arachnology the study of spiders and other arachnid s Entomology the study of insect s Carcinology the study of crustacean s Myriapodology the study of centipede s, millipede s, and other myriapod s Malacology the study of mollusk s Invertebrate paleontology the study of extinct invertebrates These divisions are sometimes further divided into more specific specialties. For example, within arachnology, acarology is the study of mite s and tick s within entomology, lepidoptery is the study of butterflies and moth s, and so on.

Tracheole tr k l is a fine respiratory tube of the Invertebratetracheatrachea of an insect . Tracheoles are about 1 m in diameter, and they convey oxygen to cells while providing a means for carbon dioxide to escape. Tracheoles branch from the larger Vertebrate trachea tracheae which can be several mm in diameter much like capillaries branch from arteries, or twigs from branches of a tree. This increases the surface area for gas exchange in the insect. Areas of intense metabolic activity, such as the digestive tract and flight muscles have very dense aggregations of tracheoles. Though usually closely associated with cells, tracheoles physically penetrate only the flight muscle cells which have the highest oxygen demands. Unlike the larger tracheae which are derived of ectodermal stem cells, tracheoles do not molt with the insect. Instead, they remain in place and fuse themselves to new tracheae at each molt by a cement they produce ref Klowden, M. J. 2007. Physiological systems in insects.
