WebThe pronephros, a vestigial kidney structure, regresses early in gestation. However, it constitutes a parallel series of pronephric tubules that extend and fuse to generate the primordium of the pronephric duct, or primary nephric duct. The pronephric duct continues to elongate until it reaches the mesonephros, forming the mesonephric duct.
