urinary bladder
Sign in to saveThe bladder () is a hollow organ in humans and other vertebrates that stores urine from the kidneys. In placental mammals, urine enters the bladder via the ureters and exits via the urethra during urination. In humans, the bladder is a distensible organ that sits on the pelvic floor.

AI overview
The urinary bladder is a hollow organ that collects and stores urine produced by your kidneys until you're ready to urinate. It matters because it allows your body to regulate when and how often you need to eliminate waste, rather than doing so continuously throughout the day.
