The part from the loop of Henley to the collecting duct is called distal convoluted tubule. Its length is 5 mm and diameter is 22.5 μ. It is surrounded by peritubule capillary or epithelial cells. It is located in the cortex. The next part of the distal patchy duct is called the collecting duct. Several collecting ducts join to form the Duct of Bellini.
