Swelling and edema often occur during which process?

• A. Inflammation
• B. Primary injury
• C. Chemical mediation
• D. Leukocyte migration

Answer: (A)

Swelling and edema occur during inflammation. When tissue is injured, inflammatory mediators such as histamine and bradykinin cause blood vessels to dilate and become more permeable. This leakiness lets fluid and plasma proteins escape into the surrounding tissue, producing edema. The fluid buildup is a direct result of the vascular changes that accompany inflammation, helping to dilute toxins and deliver immune components to the site. While a primary injury is the initial damage and chemical mediators are involved in signaling during inflammation, edema specifically reflects the vascular permeability changes that occur with the inflammatory process. Leukocyte migration occurs as part of inflammation after the vessels become permeable, but swelling is most directly tied to the inflammatory response itself.
