The urethra is a tube that connects the bladder to the outside of the body. All mammals have it. It allows the removal of urine from the body. There is a muscle (the urethral sphincter) which controls urination.
In male mammals, the urethra is also a part of the reproductive system, because males use it as a tube for sperm during sex.
