Many different immune cells can take part in an inflammation. They release different substances, the inflammatory mediators. These include the tissue hormones bradykinin and histamine. They cause the narrow blood vessels in the tissue to expand, allowing more blood to reach the injured tissue. For this reason the inflamed area turns red and becomes hot.
