Final answer:
A woman named Jane experienced the classical signs of inflammation—redness, swelling, warmth, pain, and loss of function—after a fall injured her wrist, demonstrating the body's innate immune response to tissue damage.
Step-by-step explanation:
Case study: Jane, a 42-year-old woman, presents with a swollen, tender, and warm wrist after falling and catching herself with an outstretched hand. She reports significant redness and swelling at the site of impact, corresponding pain that exacerbates with movement, and a degree of difficulty in properly flexing her wrist, indicating some loss of function. These signs align with the cardinal symptoms of inflammation, which in Jane's case are likely due to tissue damage from the fall rather than an infection. This is an example of an innate immune response where increased blood flow and chemical mediators have been directed to the injured area to facilitate healing processes, including the recruitment of phagocytic cells for clearing debris.
