ANS: 4
A sign of an acute inflammatory process is pain. The swelling of inflamed tissues increases pres-sure on nerve endings, causing pain. Chemical substances such as histamine also stimulate nerve endings, adding to the pain response. The skin is not blanched; but rather, with the increase in local blood flow; it is reddened. The symptom of localized warmth results from a greater volume of blood at the inflammatory site. The cellular response of acute inflammation involves WBCs arriving at the site. There is an increase in WBCs, rather than a decrease.
