Part 3/12:
In stark contrast to human anatomy, where decapitation is immediately fatal, certain creatures, like cockroaches, exhibit bizarre forms of resilience. Cockroaches breathe through a network of tubes called spiracles that do not rely on a centralized circulatory system. Consequently, when a cockroach is decapitated, it can continue to live for hours, responding to stimuli and even moving around with minimal discomfort. Although they eventually succumb to thirst and hunger, these remarkable insects can survive up to weeks after decapitation. This ability showcases the importance of structure and function in survival.
