Immune System

Your immunes system is a system of tissues, cells and organs that help your body defend itself against germs. Your basic immune system starts with some general defense systems against pathogens, which are germs that can make you sick. Your first part is your skin, which is really like a shield that prevents pathogens from entering you body. Another part is the mucus in your nose, which prevents pathogens getting in through your airways, while the acid in your stomach can incinerate any pathogens that are on the food you eat. When a germ is able to somehow bypass you body's basic defenses, there are always white blood cells on patrol, looking for these germs, and when they recognize a germ, they kill it before it is able to preform damage. The problem happens when your body doesn't recognize a germ and it is able to multiply and make you sick, although your immune system will soon catch on and produce antibodies which can uniquely latch on to pathogens and can either handle them themselves, or call on white blood cell to do the fighting. Sometimes with bacterial infections, you need the aid of antibiotics to help fight off the bacteria.
