Final answer:

The correct sequence through which urine flows is calyx, renal pelvis, ureter, urinary bladder, and urethra, corresponding to option B) 3, 2, 1, 4, 5. The renal pelvis is part of the kidney, not a bone. A large kidney stone blocking urine flow is likely lodged in the ureter.

Step-by-step explanation:

To correctly arrange the following structures through which urine flows, we should list them in the order that urine passes through them, starting from where urine is formed to where it's expelled from the body. The correct sequence is: Calyx (where urine collects from the collecting ducts), Renal pelvis (the funnel-shaped structure where the calyces merge and which narrows to become the ureter), Ureter (the tube that carries urine from the kidneys to the bladder), Urinary bladder (where urine is stored), and Urethra (the tube through which urine is discharged). Therefore, the correct option is B) 3, 2, 1, 4, 5.

Addressing the information provided:

  • 6.False. The renal pelvis is not a bone; it is a part of the kidney that collects urine before it passes through the ureter.
  • 7. If a person has a large kidney stone that blocks the flow of urine from the kidney to the bladder, it is likely located in the ureter, which is the structure that urine passes through after leaving the kidney and before reaching the bladder.

Matching structures with descriptions:

  • Urethra: Tube through which urine is discharged.
  • Ureter: Tube that carries urine from the kidneys to the urinary bladder.
  • Urinary bladder: Structure that stores urine before urination.
