PATHOLOGY

Detailed explanation-1: -The renal pelvis leads to the ureter on the outside of the kidney. On the inside of the kidney, the renal pelvis branches out into two or three extensions called the major calyces, which further branch into the minor calyces. The ureters are urine-bearing tubes that exit the kidney and empty into the urinary bladder.

Detailed explanation-2: -The kidney filters the blood. The formation of urine occurs in the renal pyramids. Renal pyramids are small structures that comprise several tubules and nephrons and it forms a part of the renal medulla. Urine passes through renal pyramids into the renal pelvis.

Detailed explanation-3: -renal pelvis, enlarged upper end of the ureter, the tube through which urine flows from the kidney to the urinary bladder. The pelvis, which is shaped somewhat like a funnel that is curved to one side, is almost completely enclosed in the deep indentation on the concave side of the kidney, the sinus.

Detailed explanation-4: -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.
