Asthma

Question 1

Intrinsic

Answer 1

IgE is usually only involved locally, within the airway passages

Question 2

Extrinsic

Answer 2

symptoms are triggered by an allergen (such as dust mites, pet dander, pollen, or mold). The immune system overreacts, producing too much of a substance (called IgE) throughout the body. It’s the IgE that triggers an extrinsic asthma attack.
