Get on board a flight into your own airways. You’ll go where asthma happens, into the bronchi of your lungs. Experience the flow of air into and out of your lungs and listen as asthma experts explain how that airflow can be blocked. Zoom in closer to see what your airways look like when they’re obstructed by mucus and cells of the immune system. View the muscles that wrap around the bronchi to understand how they can cut off airflow when they constrict. See how different inhalers are used, and take a close-up look at some of the microscopic allergens that can trigger an asthma attack. View pulmonary function testing and learn how to keep track of your own airflow—and how keeping it under control makes all the difference.
