What carries urine out of the body in both males and females?

The urethra is the structure responsible for carrying urine out of the body in both males and females. It is a thin tube that connects the urinary bladder to the external environment, providing a channel for urine to be expelled.

In males, the urethra also serves as the passage for semen during ejaculation, making it a dual-purpose tube. In females, the urethra is solely dedicated to the passage of urine. In both sexes, its primary function remains the same.

The other options refer to reproductive structures that do not play a role in urine transport. The vagina is part of the female reproductive system, the uterus is where fetal development occurs, and the fallopian tubes are involved in the transportation of eggs from the ovaries to the uterus. None of these are involved in the excretion of urine, which clearly distinguishes the urethra as the correct answer.
