Which organ stores excess liquid (urine) before it leaves the body?

Explanation:
Urine is stored in the bladder before it leaves the body. The bladder acts as a stretchy reservoir with muscular walls and sphincters that hold urine until you choose to urinate. Kidneys produce urine by filtering the blood, and urine then travels down the ureters into the bladder. The liver and stomach handle digestion and metabolism, not urine storage. So the organ that stores excess liquid before it exits is the bladder.
