Hello Aspirant!
You might have studied about the structure of human excretory system.
Nephron is the structural and functional unit of our kidneys. A nephron primarily consists of - renal corpuscle, PCT, loop of Henle and DCT, which empties through collecting tubules into a straight Collecting duct.
The urine formed in nephron is first collected through the collecting duct .
Numerous collecting ducts merge into the renal pelvis, which then becomes the Ureter.
Urine flows into Ureter from the renal pelvis.
Urine is then transported subsequently from the Ureter into the urinary bladder .
The Urethra finally carries the urine away from the bladder to the outside of the body.
So, the correct answer is -
3. Collecting duct ->Ureter->Urinary Bladder->Urethra
Feel free to ask in the comment section if you have any more queries.
I hope this answer will be helpful.
