How many body parts do insects have?

Insects are classified within the phylum Arthropoda, and they are characterized by having three main body regions: the head, the thorax, and the abdomen. This three-part structure is a defining characteristic of insects, which distinguishes them from other arthropods that may have different body part configurations.

The head contains sensory organs such as compound eyes and antennae, as well as mouthparts for feeding. The thorax is responsible for locomotion and bears the legs and wings, if present. The abdomen houses vital organs for digestion, reproduction, and excretion. This specific segmentation is crucial for the functionality and survival of insects in various environments.
