The first and second lines of defense are both components of innate immunity, that is defenses that are present at birth. The job of the first line of defense is to keep microbes out of the body. They include the skin, mucous membranes and their secretions and the normal flora. The second line of defense is activated once the microbe gets into the body. The second line of defense includes white blood cells (which "eat" invading microbes), inflammation (which is used to isolate the microbes and facilitate tissue repair), fever (which inhibits replication of microbes and enhances WBC performance), and antimicrobial substances.
The skin is the "first line of defense".

The first line of defense includes the skin, breathing passage, mouth and stomach.
In the immune system, the first line of defense are mechanical and physical barriers, such as the skin and the cornea of the eye. The main line of defense, meanwhile, are the innate immunity and acquired immunity of an organism.
