The word 'ventilate' means to let fresh air flow into a room or space. It is important to ventilate a room or space to remove stale air, unpleasant odors, and gases. You can open windows and doors or use a fan to ventilate a room. Ventilation is also important in hospitals, factories, and other public places to keep the air clean and safe to breathe. Overall, we should ventilate to maintain a healthy environment.
