Allergies
Allergies Objectives
-
Outline an allergic response, including allergens, antibodies, mast cells, histamine, and blood vessels.
-
Describe what occurs during primary exposure and re-exposure to an allergen.
-
Explain why allergies can be serious and list different allergy treatments.
We will begin with an overview of the most common hypersensitivity disorder: allergies.
Primary exposure to an allergen primes mast cells to respond when re-exposed to the allergen.
Allergy Treatments
If it is not possible to avoid an allergen, medications may be necessary.
This is the end of the Immunity Guide. Material from this guide and corresponding lecture, as well as the previous Defenses Systems Guide, is assessed on the weekly quiz.
