In which order does urine flow through the body?

The process of urine formation and flow through the body begins in the kidneys, which are responsible for filtering blood and producing urine. Once urine is formed, it travels via the ureters, which are tubes that connect the kidneys to the bladder. The bladder serves as a reservoir for urine, allowing it to be stored until it is ready to be excreted. Finally, urine is expelled from the body through the urethra.

In summary, the correct sequence of urine flow is from the kidneys to the ureter, then to the bladder, and lastly to the urethra. This flow not only reflects the anatomical pathway but also corresponds with the physiological functions of the urinary system. Understanding this order is crucial for comprehending how the body manages waste and regulates fluid balance.
