bladder

urethra

The correct answer is the bladder.

Explanation:

The urinary bladder is a hollow muscular sac-like an organ in the pelvis. An empty bladder appears to like a pear in size and shape. Urine is formed in the kidneys and moves to two tubes, termed ureters, downwards to the bladder. The bladder carries and stores urine and regulates urination to be controlled and infrequent.

Urine exits from to the bladder to urethra and out of the body.

Thus, the correct answer is the bladder.
