Final answer:
A local response is the immune system's reaction contained within a specific area of the body, such as the targeted activity of immune cells like B cells and T cells in the affected area. It is part of the adaptive immune system, capable of launching a specific attack against a particular pathogen.
Step-by-step explanation:
The term local response refers to a response within a specific area of the body. The correct answer to your question is B. A response within a specific area of the body.
In contrast to a systemic response, which involves multiple body systems, a local response is contained within a particular area and involves actions such as inflammation or the localized activity of immune cells. For example, when an infection occurs, immune system cells, such as B cells and T cells, may be activated in the affected area to combat the pathogen. This is part of the body's adaptive immune system, which can deliver a targeted response to a specific threat.
It's important to note that while a systemic response can impact various organs and tissues throughout the body, a local response is much more limited in scope. The immune response, particularly when speaking of the adaptive immune system, consists of specialized actions designed to specifically address and remember the pathogen for future defense.
