Detailed explanation-1: -The area at the center of the kidney. Urine collects here and is funneled into the ureter, the tube that connects the kidney to the bladder.

Detailed explanation-2: -The ureters begin at the ureteropelvic junction (UPJ) of the kidneys, which lie posteriorly to the renal vein and artery in the hilum[1]. The ureters then travel inferiorly inside the abdominal cavity.

Detailed explanation-3: -Pelvic ureter The ureter enters the pelvis, where it crosses anteriorly to the iliac vessels, which usually occurs at the bifurcation of the common iliac artery into the internal and external iliac arteries. Here, the ureters are within 5 cm of one another before they diverge laterally.

Detailed explanation-4: -From the major calyces, the urine flows into the renal pelvis; and from there, it flows into the ureter.
