IMMUNOLOGY

Detailed explanation-1: -Anaphylaxis causes the immune system to release a flood of chemicals that can cause you to go into shock-blood pressure drops suddenly and the airways narrow, blocking breathing. Signs and symptoms include a rapid, weak pulse; a skin rash; and nausea and vomiting.

Detailed explanation-2: -Anaphylaxis is a severe, systemic hypersensitivity reaction that is rapid in onset and characterized by life-threatening airway, breathing, and/or circulatory problems, and that is usually associated with skin and mucosal changes.

Detailed explanation-3: -Anaphylaxis, also called allergic or anaphylactic shock, is a sudden, severe and life-threatening allergic reaction that involves the whole body. The reaction is marked by constriction of the airways, leading to difficulty breathing. Swelling of the throat may block the airway in severe cases.
