Urinary System

Imagine trying to manage the clutter in your house by sorting, storing, and eventually discarding unwanted items. Much like this process, the urinary system organizes the body's waste management by producing, storing, and then eliminating urine. In this analogy, the items you decide to get rid of represent waste in the body, your storage spaces (like closets) are akin to the bladder where urine is held, and the act of throwing things away is similar to urination, where waste is finally expelled from the body.
