Definitions:

Nephron

The basic structural and functional unit of the kidney responsible for filtering and purifying blood to produce urine.

Distal Convoluted Tubule

The segment of the kidney's nephron that functions in the reabsorption of sodium, water, and secretion of potassium and acids, situated after the ascending limb of the loop of Henle.

Collecting Duct

A series of tubes in the kidney that receive urine from the nephrons and transport it into the renal pelvis.

Renal Pelvis

The central part of the kidney where urine collects before moving to the ureter and then to the bladder.
