Verified Solutions | Latest Updated 2026
What is the epidemiology of - affects more than 18 million Americans; 6
Asthma? million
children
- more common in Women and Boys
- higher rate in African Americans
- risk of death due to asthma increases
with age
What is Asthma? a chronic lung disease characterized by an
intermittent, reversible airway obstruction
resulting
from inflammation of the lungs airways and
tightening of the muscles that surround the
airways.
Does Asthma affect the bronchial bronchial airways
airways or the alveoli? - specifically bronchial
hyperresponsiveness
, What triggers bronchial exposure to irritants, exercise, cold
hyperresponsiveness? weather, or risk
factors.
- irritants can include smoke, mold, pollen,
dust,
animal dander, air pollutants, and
occupational
irritatns.
What are the risk factors of - viral infections
Asthma? - nasal polyps
- allergic rhinitis
- certain foods and medications
- emotional stress
What happens when Asthma the immune system activates and IgE
encounters a trigger? antibodies
bind to receptors on mast cells.
- this causes degranulation and the
release of
inflammatory mediators (histamine and
leukotrienes) - which causes vasodilation
and
increases capillary permeability.
What stimulates the production of when there's a trigger, there's an increase
mucus with Asthma? of
basophils, eosinophils, and neutrophils
that
stimulate mucus production.
- this causes a thick mucus that causes
thickening of
the airways and bronchial
hyperresponsiveness.
