urethra

The urethra is a tube that carries urine from the bladder to outside the body. In men, it also serves as a passage for semen during ejaculation. It runs through the prostate and penis, while in women, it is shorter and opens just above the vaginal opening. The urethra's primary function is to eliminate waste by directing urine out of the body, and its structure varies between sexes to accommodate reproductive functions in men. It plays a crucial role in the urinary system’s ability to remove liquid waste efficiently.
