Question

Differentiate between the Renal Pelvis and the Renal papilla.

Answer 1

Renal pelvis and renal papilla are present in the urinary system. The urine is produced by the kidney. They both play an important function of removing the urine out of the body.

Complete answer:
To solve this question, we must know the location of the renal pelvis and renal papilla.
Renal is associated with the kidney. The urine is produced in the kidney and it is transported to the urinary bladder through the ureter. Kidney is a bean shaped organ which is present in pairs in the human body. The structural and functional unit of kidney is nephron. So renal pelvis and renal papilla are present in the kidney. Let us find out the difference between them in terms of structure, location and function.

Renal Pelvis	Renal papilla
Renal pelvis is the portion formed by the union of two or three calyces.	It is the location where the renal pyramids present in the medulla empty urine into the minor calyx.
It functions as a funnel for the urine to flow to the ureter.	The collecting duct discharges the urine through papilla.
It is the region of the kidney which is mostly affected by different types of cancer.	It is associated with various other infections.

Note: The ureter collects the urine from the kidney to the urinary bladder. The urinary bladder is the sac-like structure which collects the urine. The urine is discharged to the outside through the urethra.
