Як комахи дихають без легенів? | How do insects breathe without lungs?

Insects have no lungs—so how does oxygen reach their tissues? In most species, air enters through small openings in the exoskeleton called spiracles, then travels through a branching network of tracheae and tiny tracheoles. Aquatic larvae may exchange gases through specialized gills or across the body surface, so details vary by species and life stage.
