Name the passage in sequence through which urine passes from kidneys to the outside in humans. How is urine prevented from flowing back into the ureters?
Kidneys → Tubular part of Nephron → Collecting duct → ureter → urinary bladder → urethra → outside.
The urinary bladder is under nervous control and muscular extended bladder leads to surge to pass out urine via urethra and not into ureters.
