उत्तर
urethra
Explanation:
The human excretory system comprises a pair of kidneys, a pair of ureters, a urinary bladder, a urethra and a urinary opening. Urine passes from the kidneys through two tubes called ureters into an elastic sac called the urinary bladder. The urinary bladder stores the urine temporarily, which is then excreted through the urethra.
