Life Support Systems

Life support systems are essential technologies and equipment that maintain human life in critical situations, such as in hospitals or space missions. These systems provide vital functions, including supplying oxygen, removing carbon dioxide, supporting circulation, and ensuring proper nutrition. Examples include ventilators, which help patients breathe, and dialysis machines that filter waste from the blood. In space, life support systems regulate air quality, pressure, and temperature to create a safe environment for astronauts. Essentially, they ensure that basic physiological needs are met when normal bodily functions are compromised.
