Immune system
Everything in the body that fights germs: barriers (skin, mucus, stomach acid), a fast general defence (inflammation and white blood cells that swallow germs), a slower targeted one (antibodies that stick to one germ), and immune memory that makes the next fight faster. A fever is usually part of the defence.
