Human beings are considered open systems. This means that they constantly interact with their environment and exchange matter and energy. Unlike closed systems that do not exchange matter with their surroundings, open systems allow for the flow of resources and information, which is essential for growth and survival.
For instance, humans take in food, water, and oxygen—essential elements for sustaining life—while also releasing waste products and carbon dioxide. This exchange indicates that we are not isolated or closed off from our environment; rather, we are in a dynamic relationship with it. Our bodies rely on a variety of external inputs to function properly, including social connections, emotional support, and physical resources, all of which further supports the idea of being an open system.
