The five general non-specific defense mechanisms that act quickly to fight a wide variety of invaders are:
Antimicrobial proteins
Phagocytes
Natural killer cells
Inflammation
Fever

Antimicrobial proteins are the type of proteins which fight against microbes like bacteria and parasites.
Phagocytes are the cell that engulf foreign substances when they are detected in the body.
Natural killer cells are the part of innate immune system that fight against viral infections and is responsible for host rejection of tumor.
Inflammation is mechanism of the body that occurs when foreign substances are detected in the body. Fever is the result of inflammation and immune response against microbes.
