Question

Quizplus · Accepted Answer

Anaphylaxis is a type I hypersensitivity reaction in which mast cells bound by immunoglobulin E (IgE) degranulate, releasing a variety of potentially hazardous substances into the circulation. Hives (urticaria), angioedema (swelling of mucous membranes or internal organs), and wheezing are common symptoms of anaphylaxis. The chemical mediators of anaphylaxis typically produce vasodilation and increased vascular permeability. These physiological changes usually cause hypotension (low blood pressure) rather than hypertension.
