It is very complex with numerous members that all play important roles (some of which are the B cells, macrophages, helper T cells, cytotoxic T cells, dendritic cells, eosinophil, basophil and neutrophil).
No, they are the third line of defense.

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.
The integumentary system is one of the first lines of defense against infection. It provides a physical and chemical barrier against the entry of pathogens.
