Question

Quizplus · Accepted Answer

The damaged tissues produce chemicals called mediators of inflammation, which diffuse away from the damaged area and cause any blood vessels they meet to dilate. This brings more blood flow to the area. The increased blood flow accounts for the redness and heat. Blood vessels become more permeable when they dilate. Fluid from the blood leaks out into the surrounding damaged tissue, causing it to swell. This extra fluid increases pressure on the nerve endings, creating the pain.
