Excerpt from The Biology of Insects
In several classes of the Arthropoda - the great compre hensive Group or Phylum to which insects belong - we find that the outer skin with its firm cuticle is pushed into the body in such a manner as to give rise to a series of branching air-tubes of which the firm cuticle necessarily forms the lining and prevents their channels from collapsing. As these air-tubes open to the outside through a set of breathing holes or spiracles, air can pass in and come into touch with organs inside the creature's body so that the process of oxidation becomes easy and direct; the oxygen needs not the circulating'fluid or blood to carry it from special breathing organs such as lungs or gills to the tissues where the combustion processes are constantly going on (figs. 14.
