The head and the thorax of insects are the two body parts that are smaller than the much larger abdomens that accommodate internal structures necessary for the equivalents of breathing, digesting and reproducing. The head, as the first part, contains the components necessary for eating and sensing. The thorax, as the second part, is compared to an engine or motor because of its support to legs and wings.
