The Immune System
The immune system is the body's defense system. It works on three different levels. The first level is the anatomic response. It consists of anatomical barriers to foreign particles and includes the skin and acid in the stomach. Anatomic barriers prevent foreign substances from entering the body. If foreign particles pass through the first line of defense the second line of defense called the inflammatory response kicks in. The third line of defense is the immune response. It is the main player in specific immune defense.
The cells of the immune system mount the immune response.
These cells are also called white blood cells.
