Life support systems are essential technologies that provide the necessary conditions for living organisms to survive in environments where natural support is absent or insufficient. These systems are commonly used in space missions, underwater exploration, and medical settings, ensuring that vital needs such as oxygen, temperature control, and waste removal are met. In medical contexts, life support systems can include devices like ventilators and dialysis machines, which help patients with critical health issues. In space, systems like the International Space Station's environmental control and life support system recycle air and water, allowing astronauts to live and work for extended periods beyond Earth.
