Gas exchange occurs in these tiny air sacs of the lungs.
Alveoli
This tube connects the throat to the lungs (generally called the windpipe).
Trachea
The leading preventable cause of lung disease worldwide.
This index (often reported in weather apps) tells you how polluted the air is.
AQI (Air Quality Index)
Oxygen is transported in the blood primarily bound to this molecule.
Hemoglobin
These smaller branches of the bronchi regulate airflow and resistance.
Bronchioles
This type of prevention aims to stop lung disease before it starts (e.g., anti-smoking campaigns). [primary, secondary, tertiary]
Primary Prevention
This common air pollutant from vehicles can impair lung function.
Carbon monoxide (and/or nitrogen dioxide)
This process allows gases to move across the alveolar membrane based on concentration gradients.
Diffusion
This structure prevents food from entering the lungs during swallowing.
Epiglottis
Secondhand smoke exposure increases risk for this condition in children.
Asthma (and/or respiratory infections)
Wearing this type of mask can help reduce inhalation of fine particulate matter during wildfires.
