How does the Immune system operate ?

The immune system protects you in 3 different ways:

1)It creates a barrier that prevents antigens from entering the body.

2)If an antigen (such as a Virus) does get into the body,the immune system tries to detect and eliminate it before it can make itself at home and reproduce.

3)If the Virus is able to reproduce and start causing problems,the immune system is responsible for eliminating it.
