In anatomy, the urethra (from Greek Î¿á½ÏÎ®Î¸ÏÎ± â ourá¸thrÄ) is a tube that connects the urinary bladder to the urinary meatus for the removal of fluids from the body.

In female placental mammals, the urethra is shorter and emerges at the female external urethral orifice above the vaginal opening.
