The immune system is the complex system in the body responsible for fighting disease. Its primary function is to identify foreign substances in the body ([[bacteria]], [[viruses]], [[fungi]] or [[parasites]]) and develop a defense against them. This defense is known as the immune response.
It involves production of [[protein]] molecules called [[antibodies]] to eliminate foreign organisms that invade the body.
