What describes the process of capillaries leaking plasma into an injured area?

• A. Inflammation
• B. Swelling (Edema)
• C. Congestion
• D. Oxidation

Answer: (B)

The correct answer highlights the process known as swelling or edema, which occurs when capillaries become more permeable during an inflammatory response. When tissue is injured, the body’s inflammatory response kicks in, resulting in an increase of blood flow to the area. This increased blood supply leads to the leakage of plasma, which contains water, proteins, and other substances, from the capillaries into the surrounding tissue. As this fluid accumulates, it causes the area to swell, which is a characteristic sign of inflammation.

This swelling serves as a protective mechanism, helping to isolate the affected area and facilitate healing by allowing white blood cells and nutrients to access the injured tissue. Therefore, the description of this process specifically aligns with the term "swelling (edema)," making it the most accurate choice in the context presented.
