What is inside a stick insect?

Inside a stick insect, like other insects, you'll find a segmented body comprising three main parts: the head, thorax, and abdomen. Their internal structures include a digestive system, respiratory system with tracheae, and a nervous system with a brain and ventral nerve cord. Stick insects also have an exoskeleton, which provides support and protection, and they possess specialized organs for reproduction. Additionally, they have hemolymph (insect blood) that circulates nutrients and helps with immune functions.
