Effects of Asthma on Bronchioles

Référence de la vidéo 12497945
Animation showing a 3D visualization taken from human scanned data. The camera pans down past an anterior view of the nasal passageways, and focuses in on the trachea, bronchi, and bronchioles. The bronchi and bronchioles are highlighted in red. A sectioned bronchiole is then shown developing symptoms of asthma. The bronchiole begins in a healthy state, and slowly becomes inflamed, swollen, mucus-filled. These symptoms develop when there is a blockage of air flow within the lungs. This blockage is most often caused by an excess of mucus (inflammatory cells) that show up to heal the bronchioles when they are damaged from allergy, infection, or injury. When the bronchiole pathways fill with mucus, irritation and swelling occur thus there is little room left for air. Breathing then becomes difficult and may be accompanied by wheezing or coughing.
