Answer:
The bladder is an organ in the body that has a similar function to a balloon.
Explanation:
The bladder holds urine that travels from the kidneys into the bladder. The bladder acts as a bag that holds and stores the urine. The bladder expands as it fills with urine. When it is full, the bladder sends a message to the brain through the nerves. The brain tells the body that urine is ready to be released from the body as waste.
