Question

Quizplus · Accepted Answer

Anaphylaxis is a severe and potentially life-threatening allergic reaction that can occur within seconds or minutes of exposure to an allergen such as peanuts, shellfish, bee venom, or medication. It involves a release of chemicals, including histamine, that causes a decrease in blood pressure and constriction of the airways, leading to difficulty breathing and potentially fatal consequences. Autoimmunity is a condition in which the immune system attacks the body's own healthy tissues, while allergy is a hypersensitivity reaction to a specific substance that is not normally harmful. Lymphedema is a swelling of the lymphatic system that occurs when lymph fluid does not properly drain from the body's tissues.
