How Lou Got the Flu

http://www.amnh.org/nationalcenter/infection/04_lou/04_lou.html
Infectious diseases spread from person to person and even from animal to people. This site shows how the flu virus is a microscopic hitchhiker that can travel great distances in relatively short amounts of time. For example, you can trace Lou’s flu back to Chinese ducks. Try to remember the last time you had the flu. Who had it before you? Did anyone catch it after you did? Create a chart that traces your flu as it might have traveled through your friends and family.

On the most basic level, your body is composed of millions of individual cells that work together to fulfill the complex functions of life. Blood cells carry oxygen to your muscles. T-cells train to attack invading substances and particles. This site contains hundreds of computer enhanced and microscopic images and animations of cells. Click on the “Cell Gallery” in the left navigation bar and find pictures and animations of three different types of cell functions.
