Choose the correct path of urine in our body:A. kidney → ureter → urethra → urinary bladder B. kidney → urinary bladder → urethra → ureter C. kidney → ureter → urinary bladder → urethra D. urinary bladder → kidney → ureter → urethra

Answer»

Urine from nephron is brought to the collecting duct of kidneys where the urine enters the ureters. There are 2 ureters, each opening from one kidney into the urinary bladder. The urinary bladder stores urine and it size increases as the amount of urine collected increases. When the CNS gives a voluntary message the muscles of bladder contract and the bladder sphincter relaxes thus excreting urine out through the urethra.
