About Asthma
Asthma is a chronic respiratory
disease. People who have asthma suffer from inflamed airways.
When an asthma attack occurs,
the smooth muscle cells in the
bronchial tubes constrict, the
airway tubes become inflamed,
swollen and very sensitive and
tend to react strongly to certain
inhaled substances.
About COPD
To understand COPD, it helps to understand how the lungs work.
The air that you breathe goes
down your windpipe into tubes in your lungs called bronchial tubes or airways.
Within the lungs, your bronchial tubes branch into thousands of smaller, thinner tubes called bronchioles.
Hay fever and allergies
Hay fever, like all allergic reactions, is caused by allergens, foreign "invaders" that enter your body by inhalation, by
swallowing, or through your skin.
In hay fever, the allergens are airborne substances that enter your airways (mouth, nose, throat, and lungs) via your breathing and the linings of your eyes and sometimes ears via direct contact.
