Renal pelvis

The kidneys clean the blood to take out waste and make urine. Urine collects in the renal pelvis, the area at the center of the kidney, and then passes through the ureter, into the bladder, and out of the body.

What Is the Renal Pelvis?

The renal pelvis is in the center of the kidney and is responsible for collecting the urine and feeding it into the ureters, two tubes that connect the kidneys with the bladder. The bladder holds urine until it is peed out.
