(16).jpg "Urinary System Questions And Answers! Trivia Quiz - Quiz")
The urinary system operates as a filter that eliminates toxins from the body as waste. It utilizes a series of tubes and ducts to pass the liquid through the body. The urinary system supports the whole-body and makes it work properly. If you intend to learn more about the urinary system, this is the quiz for you.
