Verified step by step guidance

Understand the key terms: Specificity refers to the ability of the immune system to target specific pathogens, while memory refers to the ability to remember past encounters with pathogens and respond more effectively upon re-exposure.

Identify the characteristics of adaptive immunity: Adaptive immunity is known for its specificity and memory. It involves the production of antibodies and the activation of lymphocytes that specifically target pathogens.

Differentiate between adaptive and innate immunity: Innate immunity is the body's first line of defense and is non-specific, meaning it does not target specific pathogens. It includes physical barriers, phagocytic cells, and inflammatory responses.

Consider the role of physical barriers: Physical barriers, such as skin and mucous membranes, are part of the innate immune system and provide a non-specific defense by preventing pathogen entry.

Evaluate the inflammatory response: The inflammatory response is a non-specific reaction to injury or infection, part of the innate immune system, and does not involve specificity or memory.
