During an embryology lecture on kidney development, the professor explains that the permanent kidney develops from two distinct tissue sources. The ureteric bud is an outgrowth from the mesonephric duct that appears around week 5. It grows toward the metanephric mesenchyme and undergoes repeated branching, with each generation of branches giving rise to progressively smaller tubular structures. The metanephric mesenchyme, in turn, differentiates to form the filtration and reabsorption apparatus of the nephron. A student asks which renal structure arises from the ureteric bud.
Which of the following structures develops from the ureteric bud?
