True or False: All organs and systems in the body are subject to anaphylaxis.

• A. True
• B. False
• C. Sometimes
• D. Not always

Answer: (A)

Anaphylaxis is a systemic, life-threatening hypersensitivity reaction. When immune mediators are released, they cause widespread effects on blood vessels and smooth muscle, which can involve the skin, airways, cardiovascular system, and gastrointestinal tract, among others. Because this reaction travels through the body and can impact many organ systems, there’s potential for involvement across essentially any organ with a vascular supply. That’s why saying all organs and systems are subject to anaphylaxis is true in the sense that a severe systemic reaction can affect multiple organ systems, even though in any single event not every organ may be affected.
