Inflammation produces localized swelling redness. heat pain. All of the answers are correct. An inflammatory response is triggered when red blood cells release pyrogens T cells release interferon. mast cells release histamine and heparin neutrophils phagocytize bacteria. blood flow to an area increases. Characteristics of specific defenses include versatility. tolerance memory. specificity All of the answers are correct

Solution

39.B)a virus-infected cell will release interferons causing nearby cells to heighten their anti-viral defenses.
