being attacked by its own troops. On the other hand, foreign
organisms that enter the body will inevitably and unexpect-
edly be assaulted by these guards.
When a complement molecule binds to a foreign body, it
changes shape. This is followed by the first protein of the com-
plement molecule binding to the invader. Later, the other pro-
teins in the complement molecule attach themselves to the
invader one by one, until the complement hunters cover the
whole surface of the invading cell. The final element of the
complement system is responsible for attacking the cell mem-
brane. This clever molecule opens a hole in the cell mem-
brane of the now defenseless foreign cell, 51 which
absorbs extracellular fluids, swells and eventually
bursts.
