Bladder Anatomy

The bladder, which is found in the lower pelvic cavity, stores urine until it’s ready to be excreted through the urethra. In men, the urethra is about 8 inches long and passes through the penis, while it’s about 1.5 inches long in women and opens at the upper aspect of the vaginal opening. When empty, the bladder’s approximately the shape and size of a pear. Before reaching the bladder, urine travels to the bladder from the kidneys through the ureters. The bladder is home to three layers of flexible, muscular walls which contract when urinating. As the bladder fills up with urine, these muscular walls expand. Interestingly, we generally start to feel the familiar urge to use the bathroom when our bladders are about halfway full; our bladders can actually hold approximately a pint of urine.
