Answer;
Renal pelvis
Explanation;
The renal pelvis or pelvis of the kidney is the funnel-like dilated part of the ureter in the kidney. It is the enlarged upper end of the ureter, the tube through which urine flows from the kidney to the urinary bladder.
-The renal pelvis is curved to one side, is almost completely enclosed in the deep indentation on the concave side of the kidney, the sinus. The large end of the pelvis has roughly cuplike extensions, called calyces, within the kidney; are cavities in which urine collects before it flows on into the urinary bladder.
