Verified step by step guidance

Understand the concept of innate defense response: Innate immunity is the body's first line of defense against pathogens and includes physical barriers, cellular responses, and chemical defenses.

Identify the components of innate immunity: These typically include physical barriers like the skin, phagocytic cells such as macrophages and neutrophils, and processes like inflammation.

Recognize the role of antibodies: Antibodies are part of the adaptive immune response, not the innate immune response. They are produced by B cells and are specific to particular antigens.

Compare the options given: Analyze each option to determine which one does not fit the description of innate immunity.

Conclude which option is not part of the innate defense response: Based on the understanding that antibodies are part of adaptive immunity, identify antibodies as the correct answer.
