Final answer:
The three vessels entering the Renal Hilum anteriorly to posteriorly are the renal vein, the renal artery, and the ureter. This arrangement is crucial for the vascular system of the kidneys, which is responsible for filtering blood and producing urine.
Step-by-step explanation:
The three vessels that enter the Renal Hilum, listed anteriorly to posteriorly, are:
- Renal vein
- Renal artery
- Ureter
The renal hilum serves as the entry and exit site for structures servicing the kidneys, including vessels, nerves, lymphatics, and ureters. The renal arteries branch out from the descending aorta and enter the kidney, where they further divide to supply blood to the nephrons. The renal veins collect cleansed blood and return it to the inferior vena cava. The ureters transport urine from the renal pelvis to the urinary bladder. This sequence of the renal vein, renal artery, and ureter corresponds to the arrangement within the hilum from front to back.
