Which structure is responsible for transporting urine from the bladder?

The structure that is responsible for transporting urine from the bladder is the urethra. The urethra is a tube that connects the urinary bladder to the outside of the body, allowing for the passage of urine during the process of urination. The urethra plays a crucial role in the urinary system by facilitating the expulsion of urine once it has accumulated in the bladder.

In this context, the other options do not serve the same function. The uterus is a muscular organ in the female reproductive system where fetal development occurs; it is not involved in urine transport. The vagina is part of the female reproductive system, serving as the canal that connects the external genitals to the uterus, and it also does not participate in urine transportation. Lastly, the term vesicle in this context incorrectly refers to small fluid-filled sacs in the body, which do not have a role related to the transport of urine either. Therefore, the urethra is the only correct structure associated with the transport of urine from the bladder.
