Final answer:
The inflammatory response can cause pain, swelling, and a local rise in temperature, as it involves the release of histamine that increases blood flow and capillary permeability. It is part of the innate immune system's rapid action against infection, and if unresolved, can lead to chronic inflammation.
Step-by-step explanation:
The inflammatory response, a fundamental aspect of the innate immune system, can cause pain, swelling, and a local rise in temperature. This occurs when tissue is injured and cellular contents are released, triggering mast cells to release inflammatory mediators like histamine, which increases blood flow and capillary permeability, leading to the classic symptoms of inflammation. It is essential to resolve the cause of inflammation in order to prevent chronic inflammation, which can lead to major tissue destruction and fibrosis. Furthermore, the inflammatory response is rapid, occurring immediately when pathogens invade the body and setting the stage for the recruitment of white blood cells, like neutrophils and macrophages, for phagocytosis to clear any pathogens and cellular debris.
