Which one among the following is the correct pathway for the elimination of urine ? '

The human urinary system is responsible for the production, storage, and elimination of urine. The process begins in the kidneys, where nitrogenous wastes like urea are filtered from the blood to form urine [1]. Once produced, urine enters the ureters, which are long, narrow tubes that connect each kidney to the urinary bladder [2]. The ureters use peristaltic contractions to transport urine downward. The urinary bladder serves as a muscular storage organ that holds the urine until it is ready to be expelled [2]. Finally, when the bladder contracts, urine is released from the body through the urethra, which acts as the terminal exit tube [1]. Therefore, the correct anatomical sequence for the elimination of urine is: Kidneys → Ureters → Bladder → Urethra.
