Which organ stores urine before it leaves the body?

Which organ stores urine before it leaves the body?

• A. Kidneys
• B. Bladder
• C. Ureter
• D. Urethra

Answer: (B)

Urine is held in a stretchy, muscular sac that acts as a temporary reservoir. This storage organ expands as urine arrives from the kidneys through the ureters, and its walls are built to accommodate increasing volume without leaking. The bladder’s smooth muscle relaxes to store urine and then contracts, with signals from the nervous system coordinating when to empty it through the urethra. This arrangement allows you to control when you release urine, rather than it moving immediately from the kidneys to the outside. The kidneys are the filtering organs that produce urine. The ureters are the tubes that carry urine from the kidneys to the bladder. The urethra is the tube through which urine exits the body.
