The Urinary System
In this video Paul Andersen gives an overview of the human urinary system. The system consist of the kidneys, ureters, bladder, and urethra. The kidneys excrete waste from the blood in urine. He explains how the nephron is responsible...

Curated OER
Urine Formation
A very scientific explanation of urine production is given in this resource. The video zooms to the nephron level in the kidneys and discusses milliosmoles and the loop of Henle. Use this video for an advanced course in medicine or anatomy.
Curated OER
Renal System, Part 3/4
The parts of the nephron are described in detail. Pictures are drawn to help your visual learners gain understanding of the function of the urinary system. This is the third of a four-part series on the renal system.
Curated OER
Kidney, Part 2
Zoom in on the nephron and see the different parts explained. Function is not touched on, simply the scientific names of structures. Show this to your anatomy class for a good close-up of a nephron.
