Verified step by step guidance

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, chemical barriers, and cellular responses.

Identify the role of fever in the immune response: Fever is a systemic response to infection that helps to inhibit the growth of pathogens and enhances the body's immune response.

Determine if fever is part of innate or adaptive immunity: Since fever is a non-specific response that occurs as part of the body's initial reaction to infection, it is considered part of the innate immune system.

Consider the characteristics of a moderate fever: A moderate fever typically ranges from 100.4°F to 104°F (38°C to 40°C) and can be beneficial in fighting infections.

Conclude whether a moderate fever is an example of an innate body defense: Based on the understanding that fever is a non-specific, immediate response to infection, it is indeed an example of an innate body defense.
