Which of these is one of the bodys first lines of defence against infections?
its killer T cells
Which one of the following participate in the bodys second line of defence?

The body's second line of defense comes into play when pathogens breach the first line of defense, which includes physical barriers like skin and mucous membranes. This response is part of the innate immune system and involves various mechanisms such as inflammation, the activation of phagocytes, and the release of antimicrobial substances. These actions help to contain and eliminate the invading pathogens. Additionally, the second line of defense is non-specific, meaning it responds the same way regardless of the type of pathogen encountered.
