What does the presence of an antigen do as part of the body’s defence system?
The presence of an antigen triggers the production of an antibody as part of the body’s defence system
Immune responses such as phagocytosis are non-specific and occur whatever the infection.
The body also has specific responses that react to specific antigens.
These are slower in action at first, but they can provide what?
