Sometimes you just have to go to the washroom. Your body has devised a complex filtering system to clean your blood of metabolic wastes. Similarly, water treatment plants will filter wastes from water through a series of filtration processes. As a result, there is a waste product that has to be disposed. How is the human body designed to rid itself of metabolic wastes dissolved in blood?

 

In this lesson you will explore the following questions:

  • What are the principal structures of the excretory system, and how do they function?

  • How do nephrons contribute to the function of the excretory system?
