inflammatory
The cut on your hand may become red, warm, and swollen. These are signs of an inflammatory response. This is the first reaction of the body to tissue damage or infection. As explained in Figure below , the response is triggered by chemicals called cytokines and histamines , which are released when tissue is injured or infected. The chemicals communicate with other cells and coordinate the inflammatory response.
