The first line of defense includes the physical barriers that prevent the entry of these antigens into the body. The second line of defense includes the leukocytes, inflammatory response and fever, and the third line of defense includes the antibodies secreted by the lymphocytes and the memory cells.

The innate immunity includes the proteins and cells which are already present in the body of a person. The adaptive immunity fights the pathogens that escape the innate immunity.
