Answer: The immune system's innate response is the first line of defense against invading pathogens. Macrophages, as part of the innate immune system, play an important role in engulfing and destroying invading pathogens such as bacteria.

Explanation:The feature of the immune system that is best described by the scenario is the innate immune response. The innate immune response is the first line of defense against invading pathogens, and it is a non-specific response that occurs immediately or within hours of exposure to an antigen. Macrophages are part of the innate immune system and are one of the first responders to a cut or injury. They play an important role in engulfing and destroying invading pathogens, such as bacteria. The innate immune response is an important mechanism for preventing the spread of infection and initiating the adaptive immune response, which is a more specific response that develops over time as the body produces antibodies against the invading pathogen.
