Overview

From Wikipedia, the free encyclopedia · Read full article · Text CC BY-SA 4.0

The bladder is a hollow organ that stores urine from the kidneys of vertebrates. In humans and other placental mammals, urine enters the bladder via the ureters and exits via the urethra. In humans, the bladder is a distensible organ that sits on the pelvic floor. The typical adult human bladder will hold between 300 and 500 ml before the urge to urinate occurs, but it can hold considerably more.
