Urethra

The urethra is a tube that carries urine from the bladder to the outside of the body. In males, it also serves as a passageway for semen during ejaculation. The length and structure of the urethra differ between males and females.

Function

The main function of the urethra is to transport urine from the bladder and release it from the body. In males, it also serves the additional function of allowing the passage of semen during ejaculation.

Anatomy

In males, the urethra is longer and runs through the penis, allowing the passage of both urine and semen. In females, the urethra is shorter and opens just above the vaginal opening.
