ntil now, we have discussed the general struc-
ture of the defence system, its organs, cells, and
enemies. In this chapter, we will explore the deadly
warfare between our defence system and enemy cells,
and the wonderful defence our body mounts.
The brave battle fought by of our defence system is
comprised of three important stages:
1. Identification of the enemy, first action.
2. The attack of the real army, all-out war.
3. Retreat to a normal state.
The defence system has to clearly identify the ene-
my before it starts the fight. This is because each en-
gagement differs from the other depending on the type
of enemy. Moreover, if this piece of intelligence is not
properly handed on, our defence system may inadvert-
ently attack the body's own cells.
The phagocytes, known as the scavenger cells of the
defence system, take the first action. They fight hand-
to-hand with the enemy. They are just like infantrymen
who fight with bayonets against enemy units.
