The renal sinus is a cavity within the kidney that contains the renal pelvis, calyces, and major blood vessels and nerves. It is located in the central region of the kidney, where urine collects before entering the ureter. The renal sinus is surrounded by renal parenchyma and plays a crucial role in kidney function by facilitating the drainage of urine and the passage of blood supply.
Renal Pelvis
A funnel-shaped sac found within the renal sinus is called the renal pelvis. It is where the urine collects before entering the ureter to be transported to the bladder.
The term for the small conical projections along the wall of the renal sinus of a kidney is "renal papilla."
The fat-filled cavities just inside the kidney's hilum are called renal sinus. They house the renal artery, renal vein, lymphatic vessels, nerves, and renal pelvis. The fat in this area helps provide cushioning and support for these structures.
Renal Sinus receives urine from the calyces.

Papillary ducts are narrow tubes in the kidney that merge to form the renal papilla. They empty urine into the renal calyces within the renal sinus.
No, the medulla is located in the inner portion of the kidney. It lies between the renal cortex and the renal sinus, and is where urine is formed and drained into the renal pelvis.
