Please select the best answer from the choices provided.



Answer :

Final answer:

Urine flows from the kidneys through the renal tubules to the ureters, gravity helps it move down to the bladder, and sphincters prevent backflow.


Explanation:

When it first leaves the kidney, urine flows through the renal tubules and then enters the ureters, not the bladder.

If you were to stand on your head, gravity would cause the urine to flow down to the bladder, and when the bladder is filled, it would be expelled through the urethra.

The presence of sphincters controls the flow of urine and prevents backflow into the kidneys.
