Final answer:
The ureteric bud develops into the ureters, calyces, and renal pelvis. These structures are integral in directing urine from the kidneys to the bladder through peristalsis, with a one-way valve system that prevents backflow.
Step-by-step explanation:
The ureteric bud is an essential structure in the embryonic development of the urinary system, and it gives rise to several key components within the urinary tract. Specifically, the ureteric bud develops to form the ureters, the calyces, and the renal pelvis. Ureters are paired tubular structures that conduct urine from the kidneys to the urinary bladder. The calyces are cup-like structures that receive urine from the collecting ducts of the kidneys, and they join together to form the funnel-shaped renal pelvis within the hilum of each kidney. This renal pelvis then narrows to continue as the ureter. These structures are significant for the proper passage and drainage of urine from the kidneys to the bladder, employing peristalsis to move urine efficiently and preventing backflow through a one-way valve mechanism.
