Dust in the Respiratory System

Ever wondered what happens when a person inhales dust?  This resource from www.teachengineering.org is a simple pictogram which describes every stage of inhalation.

The lungs are constantly exposed to danger from the dusts we breathe. Luckily, the lungs have another function – they have defence mechanisms that protects them by removing dust particles from the respiratory system. Even though the lungs can clear themselves, excessive inhalation of dust may result in occupational disease.

Everyone who tests or designs LEV should be aware of the workings of the respiratory system.
