That's Correct!
It's Wrong!
The bladder is the part of the urinary system that stores urine until it is excreted. It is a muscular organ located in the lower abdomen. When the bladder fills with urine, it expands and sends signals to the brain, indicating the need to urinate. The bladder then contracts to expel the urine through the urethra, which is the tube that connects the bladder to the outside of the body. The kidneys filter waste products from the blood and produce urine, but they do not store urine. The ureters are tubes that transport urine from the kidneys to the bladder.
