Detailed explanation-1: -From the calyxes, pee travels out of the kidneys through the ureters (pronounced: YUR-uh-ters) to be stored in the bladder (a muscular sac in the lower belly). When a person urinates, the pee exits the bladder and goes out of the body through the urethra (pronounced: yoo-REE-thruh), another tube-like structure.

Detailed explanation-2: -The urinary bladder is a temporary storage reservoir for urine. The urethra is the final passageway for the flow of urine. The flow of urine through the urethra is controlled by an involuntary internal urethral sphincter and voluntary external urethral sphincter.

Detailed explanation-3: -The correct answer: Urine is temporarily stored in the urinary bladder. Urine is constantly produced by the nephron and it is released from the kidney. The urine is removed from the kidney as ureter carries the urine away from the kidney to the urinary bladder where the urine is stored.

Detailed explanation-4: -Urine is made in the renal tubules and collects in the renal pelvis of each kidney. The urine flows from the kidneys through the ureters to the bladder.
