▪ kidney anatomy
also called  Archinephric Duct,  

      one of a pair of tubes that carry urine from primitive or embryonic kidneys to the exterior or to a primitive bladder. In amphibians the reproductive system encroaches on the Wolffian duct; in some species the duct carries both urine and sperm, but most amphibians develop a separate tube to carry urine from the kidney.

      In advanced vertebrates the Wolffian duct develops in conjunction with the embryonic kidneys. The mature kidney drains through the ureter, however, and the Wolffian duct develops into parts of the male reproductive system, such as the epididymis and the vas deferens.
