Asthma is a disease that affects the airways of your lungs. With asthma, your airways’ lining tends to always be in a hypersensitive state characterized by redness and swelling (inflammation).
HISTOPATHOLOGY OF ASTHMATIC AIRWAY Asthma is considered in terms of its hallmarks of reversible airflow obstruction, non-specific bronchial hyperreactivity and chronic airway inflammation (American Thoracic Society, 1987).
1 / 22. Asthma is a long-term problem in the tubes that carry air into your lungs that can make it hard for you to breathe. These airways get so narrow that air can’t move freely. It can cause serious wheezing and breathlessness, known as asthma attacks. There’s no cure, but most people can control their symptoms.
