The function of the first line of defense is to keep pathogens out of the body.
The third line of defence against pathogens is called the Specific Immune Responce
B-cells produces antibodies that target specific pathogens so t-cells can then recognize it and consume it.
The Body's first line defense acts as physical barriers, in which it functions by trapping the pathogens and blocking them from entering the body. Also, all first line defenses act the same way to all pathogens, in which they're called non-specific defense.
the body's second line of defense against pathogens is the B cells.

a diseas that can be passed from one living thing to another is an infectious disease
No its nonspecific. The cillia wave to move mucous up the airways creating what is known as the mucocilliary escalator which pushes pathogens and debrie up to the pharynx where it is then swallowed from and ends up in the stomach where it is destroyed. As this is the case for all pathogens and not any particular one it is nonspecific. Specific defenses are things like the actios of antibodies and lymphocytes.
