Quizplus · Accepted Answer

Urine leaving the renal papilla is collected in the cuplike structures called calyces, which are part of the renal pelvis. The renal pyramids are cone-shaped structures that make up the medulla of the kidney and contain the nephrons, while renal columns are the extensions of the renal cortex that project inward between the pyramids. The ureters are the tubes that carry urine from the kidneys to the bladder.
