It is true that the collecting tubules merge to form the ducts of Bellini.
Papillary ducts or collecting ducts or the renal collecting tubules were formerly known as the ducts of Bellini. They are structures which are present in the distal portion of the collecting ducts in our kidneys.
These ducts are formed when collecting tubules merge. They receive the renal filtrate, which is the precursor to urine, from a number of medullary collecting ducts and it empties into a minor calyx. These ducts regulate the reabsorption of water and also balances the electrolytes.
