The body has excellent defense mechanisms. When a person is well hydrated, you eat healthy foods, exercise regularly, your pH stays around 6.5 to 7.2, are happy, productive, meditative and at peace, your body is able to stop the cold and flu invaders.
When you get the flu or a cold, viruses are the cause.
What happens to these invaders inside the body?
Viruses get caught in mucus, lymph or blood and other fluids inside your body and are destroyed by your immune system. (see live first time video video). Other viruses get expelled in coughs and sneezes. If the immuno- defense systems are weakened, the body tissues are invaded and its targeted cells are turned into tiny factories that help spread the disease.
In this animation, NPR’s Robert Krulwich and medical animator David Bolinsky explain how a flu virus can trick a single cell into making a million more viruses.

David Bolinsky and his team at XVIVO designed this animation for a research company called Zirus (and we thank Zirus for letting us play with their pictures). Bolinsky says what you see in the video actually happens much, much faster in real life — in a fraction of a fraction of a second. So this is a very slow motion version of cellular activity.
Color has been added to proteins, DNA, organelles, and the teeny things inside a human cell are so small, and the insides of cells are so dark, that for all practical purposes, they are colorless.
