Earthquakes. Mechanism of Urine Concentration. A major function of the kidney is conservation of water by increasing the solute concentration in the urine.
This is accomplished by the action of about a million nephrons working together with their attached collecting ducts. Although the process is much more complex than pictured here, it helps to understand the underlying concept if we break the process down into its three essential steps. It is important to realize that in reality, all three steps are going on at the same time. To the right of the animation is a complete set of controls, so that you can focus on any part of the process that you want. Click on the "Run" button to begin.

We have been increasingly using Flash animations for illustrating Physics content.
This page provides access to those animations which may be of general interest. The animations will appear in a separate window. The animations are sorted by category, and the file size of each animation is included in the listing. Also included is the minimum version of the Flash player that is required; the player is available free from The categories are: In addition, I have prepared a small tutorial in using Flash to do Physics animations.
LInks to versions of these animations in other languages, other links, and license information appear towards the bottom of this page.
