Bill Nye the Science Guy will make you all better – with the “Germs” episode.
Don’t panic, but germs are all around you. Germs are bacteria, viruses, protozoa, and fungi, very small one-celled organisms. Your skin keeps most of these organisms from ever getting into your body. If germs slip inside, your body has some powerful weapons to attack and destroy them. And not all germs are bad; there are good germs, too, like the ones that live in our stomach and intestines – our guts.
Your body’s immune system protects you from getting sick. Special cells called neutrophils, macrophages, and lymphocytes kill germs. Proteins called antibodies attach themselves to germs, marking them. Then neutrophils, macrophages, and lymphocytes can do their duty and attack the marked germs. There’s a whole army of different cells in your body fighting the war against germs.
So don’t be illin’ – just watch the “Germs” episode.
