WebCollecting ducts are lined with cuboidal epithelium containing two cell types: the principle cells (bright staining cytoplasm) and intercalated cells (dark staining cytoplasm). The intercalated cells are scattered in the epithelium and participate in acid-base homeostasis. Type A intercalated cells are specialized for proton secretion. WebOct 25, 2024 · Here, several ducts merge to form a single large papillary duct (of Bellini), which opens into the minor calyx through the area cribrosa.

The segments of the system are as follows: With respect to the renal corpuscle, the connecting tubule (CNT, or junctional tubule, or arcuate renal tubule) is the most proximal part of the collecting duct system. It is adjacent to the distal convoluted tubule, the most distal segment of the renal tubule. Connecting tubules from several adjacent nephrons merge to form cortical collecting tubules, and these may join to form cortical … WebNov 1, 2024 · The papillary ducts drain into the renal pelvis. The pelvis is lined by a specific type of multilayered epithelium named urothelium (Fig. (Fig.16). 16).
