B cells fight germs and viruses by making Y-shaped healthy proteins called antibodies that neutralise an invader or tag it for attack by other parts of the body immune system.

After that there are T cells. These coordinate as well as execute assaults on infected cells. Helper T Cells call reinforcements by sending out chemical messages known as cytokines. Awesome T-Cells are the front line soldiers, trained, as the name recommends, to ruin the enemy.
