Did you know ants don’t have lungs? Instead of breathing like humans, ants use tiny openings called spiracles connected to a tracheal system that delivers oxygen directly to their cells. This fascinating insect respiratory system is one of nature’s most efficient biological designs. Unlike mammals, ants don’t rely on blood to transport oxygen — making their breathing process completely different from human lungs. In this short science explainer, discover: • How ants breathe • What spiracles are
