SpletSome aquatic insects with an open tracheal system carry gas gills with them (e.g. bubbles of air); these may be temporary or permanent (section 10.3.4). The volume of the tracheal system ranges between 5% and 50% of the body volume depending on species and stage of development. The more active the insect, the more extensive is the tracheal system. SpletInsect respiration is independent of its circulatory system; therefore, the blood does not play a direct role in oxygen transport.
