Which word or phrase best describes the function of the urinary bladder?

1)filter
2)storage tank
3)blender
4)passageway

I think #4, can you check for me?
Thanks.

I would not have chosen that one. I think passage way refers to something like the breathing system we have.

Of course! To determine the correct answer, let's analyze the options and the function of the urinary bladder:

1) Filter: The urinary bladder does not filter anything. Its main function is to store urine produced by the kidneys.
2) Storage tank: This option seems to be a likely choice. The urinary bladder acts as a storage tank for urine before it is eliminated from the body.
3) Blender: The urinary bladder does not blend anything, so this option can be eliminated.
4) Passageway: While the urinary bladder is part of the urinary system, it is not primarily a passageway. It serves as a temporary storage organ between the ureters (which carry urine from the kidneys) and the urethra (which eliminates urine from the body).

Based on the analysis, the most appropriate description for the function of the urinary bladder is option 2) "storage tank."
