The Respiratory System and Building Ventilation: The lungs in a biological organism take in oxygen and expel carbon dioxide, ensuring the organism's cells have the air they need to function. Similarly, a building's ventilation system exchanges stale air for fresh air, maintaining an optimal internal atmosphere. Proper ventilation prevents the "build-up" of harmful gases or pollutants, just as the respiratory system ensures harmful substances are expelled from the body.
