the disease invades them and our body
the skin keeps out most pathogens

AIDs.
White blood cells are the good cells in the body. Yes you do need red and white blood cells, but the white ones fight off diseases or pathogens. If white blood cells cannot do this then the immune system fails. The pathogens depending on their severity, could hurt the body very much. Doctors do different tests and procedures to help this not happen. White blood cells are needed to protect the body from pathogens. When they cannot stop the invading pathogens, a person will most likely get sick. on NovaNet I'm pretty sure that the answer is the person will die:))
the white blood cell protects the body against invading pathogens.
A run away infection. Such is the fate of untreated AIDSvictims.
The main function of white blood cells (also commonly referred to as leucocytes) is to defend against foreign invading pathogens that may enter the body. They do this as they are phagocytes, in that they engulf pathogens and destroy them. Therefore, the function of a white blood cell is to defend the body against infection.
Most of the white blood cells are phagocytic in function. But white blood cells like lymphocytes produce antibodies and are responsible for the immune response of the body.
B-cells and T-cells can both kill the invading bacteria. B-cells:- create antibodies which kill the bacteria. T-cells:-attack them directly or call in white blood cells. The T-cells also remember the T-cells also remember the type of bacteria and then protect themselves from that bacteria invading again. I hope this answered your question, and helped you out. :)

White blood cells protects us (humans) by preventing pathogens from entering the body.
