Verified step by step guidance1
Understand the concept of innate immunity: Innate immunity is the body's first line of defense against pathogens and is non-specific. It includes physical barriers, cellular responses, and soluble factors.
Identify the components of innate immunity: The skin barrier, phagocytic cells (like macrophages and neutrophils), and the complement system are all part of the innate immune response.
Differentiate between innate and adaptive immunity: Innate immunity is immediate and non-specific, while adaptive immunity is specific and involves memory. Antibody production is a key feature of adaptive immunity.
Recognize the role of antibodies: Antibodies are produced by B cells in response to specific antigens and are part of the adaptive immune system, not the innate immune system.
Conclude which option does not belong to innate immunity: Since antibody production is part of the adaptive immune response, it is not an innate immune response.
