Innate immunity provides the first line of defense against pathogens. It has nonspecific defense mechanisms that include soluble proteins such as complement and physical barriers such as skin and mucous membrane. It also includes cells like macrophages (involved in phagocytosis) and natural killer cells (promote apoptosis) and inflammatory response. Lysozyme is also included in innate immunity. It is present in lacrimal secretions of eye and is bactericidal.
Antibodies are a part of the adaptive immunity. They are specific in their actions towards a particular pathogen.
