Title: Collecting ducts (XVIII) in the human kidney
Description:
(A): Scheme of nephron with focus on the orange painted collecting duct.
(B): Stain Azan, inner stripe of outer zone of the medulla showing cross-sections of various tubules such as OMCD, ATL, DTL.
(C): Electron micrograph of CCD with dark (1) and light (2) principal cells and one dark intercalated cell (3).
(D): Electron micrograph of collecting duct (CD) with a light principal cell.
(E): Electron micrograph of CD with two adjacent light principal cells.
(F): Electron micrograph of CD with a light intercalated cell (IC). Note apical vesicles and microvilli (microridges or microplicae).
(G): Electron micrograph of CD with a dark principal cell.
Background: The principal cell type is involved in the Na/K balance regulated via Na-channels and K-channels, under influence
of aldosterone. Vasopressin affects the aquaporin channels.
The intercalated cells (α- and β- variants) are involved in H+/K+ exchange and Cl-/HCO3- respectively and thus contribute to the
acid-base balance (acidosis and alkalosis).
Keywords/Mesh: urinary system, kidney, collecting duct, light principal cell, dark principal cell, light intercalated cell, dark intercalated cell, histology, electron microscopy, POJA collection
