Final answer:
Slowed blood flow is NOT involved in an inflammatory response; instead, blood flow increases to deliver white blood cells to the site of infection.
Step-by-step explanation:
The option that is NOT involved with an inflammatory response is B. slowed blood flow. In fact, during the inflammatory response, blood flow to the affected area increases. This is because inflammation involves the dilation of blood vessels, which enhances the delivery of white blood cells to the site of infection and contributes to the redness and warmth characteristic of inflammation. Fever can be a systemic effect of inflammation but is not one of the cardinal local signs which include redness, heat, and swelling, among others.
Inflammation is a complex biological response of the body's immune system to harmful stimuli such as pathogens, damaged cells, or irritants. The inflammatory response is a protective mechanism that involves immune cells, blood vessels, and molecular mediators with the aim to eliminate the initial cause of cell injury, clear out damaged cells and tissues, and to initiate tissue repair.
