Final answer:
The renal pelvis emerges from the kidneys through the renal hilum. It funnels urine into the ureter via peristalsis. The renal arteries and veins are also connected to the kidneys through the renal hilum to supply and carry away blood.
Step-by-step explanation:
Through the renal hilum, the renal pelvis emerges from the kidneys. The renal pelvis is formed from the major and minor calyxes in the kidney, and it funnels urine into the ureter via peristalsis. The renal arteries and veins also emerge from the renal hilum, supplying oxygenated blood and carrying away filtered blood from the kidneys.
