which of the following is(are) classified as an accessory organ of the urinary system?
○ ureters
○ urinary bladder

○ all of the above

Explanation:

Question 139

To solve this, we recall the urinary system anatomy:

• Renal column: part of kidney's internal structure, not a tube for urine transport.
• Renal pelvis: funnel - shaped structure in kidney, not the tube to bladder.
• Urethra: tube from bladder to outside, not from kidney to bladder.
• Ureter: the tube that carries urine from kidney to urinary bladder.

The urinary system has primary organs (kidneys) and accessory organs. Ureters (carry urine from kidneys to bladder), urinary bladder (stores urine), and urethra (carries urine out of body) are all accessory organs that support the kidneys' function. So all of the listed organs are accessory organs of the urinary system.

Answer:

D. ureter
