Asthma. Computer artwork of allergens (green) in the airways of the lungs. Allergens, such as dust and pollen, can trigger an asthma attack. Small projections, called cilia (pink), line the airways and beat rhythmically to move allergen particles out of the lungs towards the throat. Asthma is a condition in which the small airways of the lungs (bronchioles) constrict making it difficult to breathe.
