What path does urine take from the kidneys to the urethra?

After urine is produced in the nephrons of the kidney, it follows a specific path through the renal system to be excreted from the body:

• Collecting Tubules: Urine flows from the nephrons into collecting tubules, which open onto the papillae of the renal medulla.12
• Calyces: The fluid enters the minor calyxes, which then drain into the major calyxes.1
• Renal Pelvis: These major calyxes open into the renal pelvis, the expanded upper portion of the ureter.12
• Ureter: Peristaltic waves of contraction move the urine down the ureter, a narrow muscular tube that transmits urine from the kidney to the bladder.134
• Bladder: The urine is stored in the urinary bladder until it is ready for elimination.45
• Urethra: Finally, the urine is voided from the bladder through the urethra, which leads to the exterior of the body.245
