Insect Anatomy

Facts about Insect Anatomy, There are many variations of insects through out the world, but most species have very similar body structure and features.

Supported by an exoskeleton insects have segmented bodies. The exoskeleton is made stiff and rigid from a covering called chitin. A head, thorax, and an abdomen make three components of an insect body structure.

The head contains the following: compound eyes, sensory antennas, and three sets of varying appendages making up the mouth.

The thorax has six segmented legs and if it is a wing insect, two or four wings. The insect abdomen houses the digestive, respiratory, excretory, and reproductive internal organs.

Although most insects body structure is very similar there are variations in the wings, legs, antennae, and mouth parts.
