| description | any structural anomaly of the kidney ducts lined by simple cuboidal epithelium that collect urine from the distal convoluted tubules, merge and become larger as they descend from the renal cortex into the medulla, and respond to vasopressin and aldosterone to regulate water, electrolyte and acid-base balance; each cortical collecting duct joints with other ducts to make a medullary connecting duct, which eventually drains into a papillary duct, emptying urine into the renal pelvis for drainage into the ureter |
