You can understand from this how is your urine collecting.....

Collecting Duct and Renal Pyramid
▪️Fluid from thousands of nephrons merges in the collecting ducts and flows through the renal pyramid, now formed as urine.

▪️ Renal Pelvis to Ureter
Urine gathers in the renal pelvis and travels down the ureter to the bladder, completing the kidney's filtration process.
