1. It can remember the aggressor and acts specifically against certain antigens. ... This way the defense responses of the adaptive immune system are more efficient and faster than those of the innate defense, if the antigen is already known.
2. Fevers may also slow down the reproduction of some bacteria and viruses. Whether the mechanism is as complex as fever and inflammation or as simple as physical barriers and phagocytosis, all nonspecific defenses provide the body with general protection against foreign invaders.
3. Antigens are substances (usually proteins) on the surface of cells, viruses, fungi, or bacteria. ... Your immune system learns to see these antigens as normal and usually does not react against them. INNATE IMMUNITY. Innate, or nonspecific, immunity is the defense system with which you were born.
4. Antibodies attach to a specific antigen and make it easier for the immune cells to destroy the antigen. T lymphocytes attack antigens directly and help control the immune response. They also release chemicals, known as cytokines, which control the entire immune response.
Hope this helps.
