Excretory System and the Nephron
Join the Amoeba Sisters as they explore the excretory system! This video will first discuss two major functions of the excretory system before focusing on the nephron. The majority of this video will tour through the nephron while...

Organ Systems
Paul Andersen explains how organs work together to form organ systems and how organ systems work together to form organisms. The kidney and bladder work together to filter blood in the excretory system. The circulatory and respiratory...

Chemical Filtration
We look at how chemical filtration can be used to remove contaminants from water. Potassium permanganate is used as the contaminant. First, we try to remove it using physical filtration, with filter paper and a funnel. This does not...

Gravity Filtration and Vacuum Filtration
The first laboratory technique that we will learn together is a very simple one, filtration. This is how we separate a mixture of liquids and solids. There are two common ways a chemist will perform filtration, those being gravity...

The Urinary System
So the digestive system gets rid of waste from the food you eat through defecation. But lots of waste will also build up in the bloodstream as a byproduct of metabolism and other processes. What does the body do with this? It will...
