== Collecting Ducts ==

'''Collecting ducts''' (pronunciation: kuh-lek-ting duhkts) are a component of the [[nephron]], the functional unit of the [[kidney]]. They play a crucial role in the regulation of [[water balance]], [[electrolyte balance]], and [[acid-base balance]] in the body.

=== Etymology ===

The term "collecting duct" is derived from its function of collecting the filtrate from the [[distal convoluted tubule]] and transporting it to the [[renal pelvis]].

=== Function ===

Collecting ducts are responsible for the final adjustment of the [[osmolarity]] and volume of urine. They reabsorb water and certain ions to maintain the body's electrolyte balance, while other substances, such as [[urea]] and [[potassium ions]], are secreted into the urine.

=== Structure ===

Collecting ducts are composed of two cell types: principal cells and intercalated cells. Principal cells are responsible for the reabsorption of [[sodium ions]] and water and the secretion of potassium ions. Intercalated cells, on the other hand, help regulate the body's pH by reabsorbing [[bicarbonate ions]] and secreting hydrogen ions.
