Question

Quizplus · Accepted Answer

Chemical mediators of anaphylaxis are molecules found in basophils and mast cells such as histamine, leukotrienes, and prostaglandins. They are released during an allergic reaction and cause symptoms such as swelling, itching, and low blood pressure. Antigens, complement proteins, and antibodies are all involved in the immune response but not specific to anaphylaxis. Antigen-antibody complexes are also important in immune reactions but are not the primary chemical mediators of anaphylaxis.
