Final answer:
The correct answer for the function of Sam's inflammatory response after being stabbed with an inoculating needle is to isolate any damage done by pathogens and to facilitate tissue repair. Inflammation is the body's natural defense mechanism involving phagocytic cells clearing debris and preventing the spread of infection.
Step-by-step explanation:
After being stabbed with an inoculating needle, Sam's finger exhibited pain, redness, heat, and swelling. These symptoms are indicative of an inflammatory response, which serves as the body's initial reaction to tissue damage or potential infection. The primary function of this type of response is to establish a physical barrier against the spread of infection, as well as to initiate tissue repair. Inflammation activates phagocytic cells, such as neutrophils and macrophages, to clear out cellular debris, pathogens, and initiate the healing process.
In Sam's case, the correct answer to the question would be: A. to isolate any damage done by pathogens introduced when the puncture occurred. Inflammation facilitates the transport of antigens to lymph nodes and prepares the wound for healing by allowing entry of clotting factors, thus promoting the recovery of the injured tissue.
