The urinary system regulates the amount of water and dissolved salts in the body and removes waste materials produced in the cells from the blood. The simulation will introduce you to the urinary system, and teach you about the urine-production process.
The simulation has four descending levels of detail: body, urinary system, kidney, and nephron.

Instructions:

1. Click on the magnifying glass in each diagram, to move to the next lower level of detail.
2. Alternatively, on the right-hand side, click on the desired level of detail to access it.
