Verified step by step guidance

Understand the difference between innate and adaptive immunity. Innate immunity is the body's first line of defense and is non-specific, while adaptive immunity is specific and involves memory cells that target specific pathogens.

Identify the role of each cell type mentioned in the problem: Natural killer cells, Neutrophils, B cells, and Macrophages.

Natural killer cells are part of the innate immune system and are involved in the destruction of virus-infected cells and tumor cells without prior sensitization.

Neutrophils are also part of the innate immune system and are the first responders to infection, primarily involved in phagocytosis and destruction of pathogens.

B cells are a type of lymphocyte that are involved in adaptive immunity. They produce antibodies specific to antigens and have memory capabilities, allowing for a faster response upon re-exposure to the same pathogen.
