Detailed explanation-1: -The collecting ducts amass contents from multiple nephrons and fuse together as they enter the papillae of the renal medulla.
Detailed explanation-2: -Correct answer: The collecting duct of a nephron is normally impermeable to water. In the presence of antidiuretic hormone (ADH), aquaporin proteins are inserted, making the collecting duct permeable to water.
Detailed explanation-3: -Renal collecting ducts are microscopic passages that connect to multiple nephrons. Tubular fluid passes through the collecting ducts to reach the calyces and renal pelvis. While traveling through the collecting ducts, the composition of tubular fluid undergoes alterations.
Detailed explanation-4: -The collecting duct is the final part of the nephron; however, it is not individual to each nephron. The distal convoluted tubules of several nephrons will join to one collecting duct, and it is several of these ducts that will fuse at the renal papilla to empty into the minor calyces.
