Which term describes hives?

Explanation:
Hives are described as urticaria. This condition presents as itchy, raised welts on the skin caused by superficial edema due to histamine release from mast cells. The lesions tend to be transient and can migrate as new wheals appear and others fade. Angioedema is deeper swelling of the skin and mucous membranes, not the superficial wheals that define urticaria. Bronchoconstriction refers to narrowing of the airways, a feature of severe allergic reactions, and epinephrine is a treatment for those emergencies, not the description of hives. So, the term that describes hives is urticaria.
