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

killer cells
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:))
A run away infection. Such is the fate of untreated AIDSvictims.
White blood cells can attack microbes within the bloodstream, tissues, and lymphatic system. They can also migrate to infected tissues and organs to combat invading pathogens.
A macrophage is the type of white blood cell that surrounds and kills invading cells.
The number of white blood cells increase during an infection, so they can fight off the pathogens quicker.
During an infection, the number of white blood cells typically increases. This is because white blood cells are a crucial part of the immune system's response to fight off the invading pathogens. The increase in white blood cells helps to combat the infection and restore the body back to its healthy state.
Antibodies are released by B-lymphocytes (one of thekinds of white blood cells)
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.
White blood cells can get to the site of infection through a process called chemotaxis, where they are attracted to the area by chemical signals released by the damaged tissues or invading pathogens. Once they reach the infection site, white blood cells can engulf and destroy the invading microorganisms to help fight the infection.
