First, various types of phagocytes, which are called the "the eater cells" will swing into action. Then the macrophages, another specific type of phagocytes, take their turn. They all destroy the enemy by engulfing it. Macrophages also perform other duties such as summoning other defence cells to the battleground, and raising the body temperature. The rise in temperature at the onset of a sickness is very important, for the afflicted the person will feel fatigued by it and need to rest, thus reserving the energy needed to fight against the enemies.
If these elements of the immune system prove insufficient against the enemies penetrating the body, then lymphocytes, the champions of the system, come into play. Lymphocytes are of two types; B cells and T cells. These are again further divided into sub groups.
The helper T cells are next in reaching the battleground after the macrophages.
