Insect physiology

Insect physiology refers to the bodily functions and systems that allow insects to survive. Insects have an exoskeleton made of chitin, providing protection and support. They breathe through tiny openings called spiracles, leading to a network of tubes (tracheae) that deliver oxygen directly to their tissues. Insects have a segmented body divided into three parts: head, thorax, and abdomen. Their nervous system is centralized, with a brain and ventral nerve cord. They have specialized organs for sensing their environment, such as antennae for smell and compound eyes for vision, allowing them to interact effectively with their surroundings.
