Our health is constantly under threat from tiny invaders that can make us very, very ill. You may not notice it, but the body is often a fierce battle ground, with miniature defenders protecting us against miniature attackers. These defenders make up an essential part of the immune system, which helps to keep us in good health.

We don’t notice that they are even there but we would soon notice if, for whatever reason, they disappeared.
