Anatomy And Physiology Quiz: The Urinary System!

Welcome to this anatomy and physiology quiz on the urinary system! The urinary system is charged with the production of urine, which helps in excreting waste thanks to the kidney. It is quite normal for people to live on one kidney if they choose to donate it or one fails. Did you know that all the blood in our body is filtered through the kidney more than a hundred times a day? Take this quiz and learn more about the kidney.
