What is the function of head thorax and abdomen?

The head, thorax, and abdomen are the three main body segments of insects. The head houses sensory organs, such as compound eyes and antennae, as well as mouthparts for feeding. The thorax is responsible for locomotion, containing three pairs of legs and often wings, enabling movement and flight. The abdomen contains vital organs for digestion, reproduction, and excretion, playing a crucial role in the insect's overall physiology.
