Definitions:

Renal Papillae

Renal Papillae are the apex of the renal pyramids in the kidneys that project into the minor calyx, playing a crucial role in the transport of urine to the ureter.

Minor Calyces

Small cup-shaped structures in the kidney where urine collects before passing into the major calyces.

Distal Convoluted Tubule

A twisted section of the nephron in the kidney where the final adjustments in the composition of urine are made.

Loop Of Henle

U-shaped part of the nephron extending from the proximal to the distal convoluted tubule and consisting of descending and ascending limbs. Some of the loops of Henle extend into the renal pyramids.
