In which order should the urinary system structures be presented following the flow of urine?

The flow of urine through the urinary system begins in the kidneys, which are responsible for filtering blood to produce urine. Once urine is formed, it passes through the ureters, which are tubes that transport urine from the kidneys to the bladder. The bladder serves as a reservoir, storing urine until it is ready to be excreted. Finally, urine exits the body through the urethra.

Thus, the correct sequence is: kidney, ureters, bladder, urethra, illustrating the pathway that urine takes from its formation in the kidneys to its elimination from the body. Understanding this process is essential for grasping how the urinary system functions in maintaining fluid balance and waste excretion.
