The correct path of urine drainage is

Collecting duct Papillary duct Minor calyx Major calyx Renal pelvis Ureter Urinary bladder
Filtrate formed by the nephrons drain into large papillary ducts from collecting duct. The papillary ducts drain into cuplike structures called minor and major calyces. Once the filtrate enters the calyces it becomes urine because no further reabsorption can occur. From the major calyces, urine drains into a single large cavity called the renal pelvis and then out through the ureter to the urinary bladder.
