Ureteric bud

The ureteric bud is an education in the fetus during organogenesis of the urinary tract. It arises near the cloaca from the Wolffian duct, the human fetus in approximately 5 weeks of age. The ureteric bud grows around the cap-like system of the kidney, specifically the metanephros ( metanephrogenes blastema ), where it induces the development of the actual kidney in amniotes. The ureter is then divided into two buds merge partially.

From the ureteric bud to form the ureter ( ureter ), the renal pelvis, the corridors of the renal papillae ( papillary duct ), the collector pipes and their connectors.
