White Blood Cells
The immune system needs to destroy the pathogens. Other wise the pathogens will multiply in the body of host. The pathogens will multiply by geometrical proportion. With in very short time the pathogens will occupy the whole body. You can no longer survive in that case.
The major functions of the excretory system is to remove wastes from the body and prevent pathogens from entering and exiting the body.
The molecules on pathogens that enable the immune system to distinguish one kind of pathogen from another are called antigens. Antibodies destroy pathogens by binding to the antigens on the pathogen.
The immune system can destroy pathogens before they can cause disease. It does this through mechanisms such as the production of antibodies, activation of immune cells like T cells and macrophages, and the release of cytokines to trigger an immune response against the pathogens.

Vaccines do not destroy pathogens, they give the immune system antibodies so it can destroy a pathogen before it causes an infection. Vaccines do exist for some bacterial infections.
The major functions of the excretory system is to remove wastes from the body and prevent pathogens from entering and exiting the body.
white blood cells, called lymphocytes, destroy pathogens and protect against future infections
white blood cells, called lymphocytes, destroy pathogens and protect against future infections.
You have spyware on your system. Clean yourself with Spybot search and destroy.
B lymphocytes, a type of white blood cell, are responsible for producing antibodies. These antibodies bind to specific pathogens, like bacteria or viruses, marking them for destruction by the immune system.
The type of cell in the respiratory tract that functions as phagocytes is the macrophages. Macrophages are part of the immune system and play a crucial role in engulfing and destroying pathogens and foreign particles that are inhaled to help protect the body from infections.
