Explanation:

The second line of defense in the immune system includes fevers, which are part of the innate (non - specific) immunity. Innate immunity is the body's first, non - specific response to pathogens. The second line of defense is activated when the first line (physical barriers like skin) is breached. Fever is a general response (not specific to a particular pathogen) that helps the body fight infection.

Second; Innate.
