Verified step by step guidance1
Understand the context: The problem is asking about physiological responses such as local swelling, increased blood flow, and fever.
Identify the key terms: These symptoms are typically associated with the body's immediate response to injury or infection.
Recall the definition: An inflammatory response is a non-specific defense mechanism that involves these symptoms to protect the body from further injury or infection.
Differentiate from other immune responses: Active and passive immunity involve the presence of antibodies, while cell-mediated and humoral immunity are specific immune responses involving T-cells and B-cells, respectively.
Conclude that the symptoms described (local swelling, increased blood flow, and fever) are characteristic of an inflammatory response, which is part of the body's innate immune system.
