Alveoli—The small air sacs clustered at the ends of the bronchioles in the lungs, in which oxygencarbon dioxide exchange takes place.
Aspiration—When solids or liquids that should be swallowed into the stomach are instead breathed into the respiratory system, or when substances from the outside environment are accidentally breathed into the lungs.
Sputum—Material produced within the alveoli in response to an infectious or inflammatory process.
