Question

Quizplus · Accepted Answer

When a cut or wound occurs and causes bleeding, the body's first line of defense is inflammation. Inflammatory mediators are released that cause blood vessels to dilate, leading to increased blood flow and the recruitment of immune cells, including phagocytes. Phagocytes, such as macrophages, are capable of engulfing and destroying invading microbes to prevent infection. Therefore, phagocytosis in the inflammatory response would participate in eliminating contaminating microbes. The other choices are also defenses against pathogens, but they are not directly involved in the elimination of microbes in a wound.
