Question

Quizplus · Accepted Answer

The swelling and raised areas are a result of histamine release and inflammation caused by the fire ant bites. This is an example of the innate immune response, which is the body's first line of defense against pathogens and other threats. The innate immune response includes physical barriers (like skin), the activation of phagocytes (like neutrophils and macrophages), and the release of immune mediators (like histamine and cytokines), all of which work together to eliminate or contain the threat.
