The Urinary bladder controls the elimination of urine from the body.
- The lower abdomen contains this triangle-shaped, hollow organ. Ligaments that are connected to the pelvic bones and other organs hold it in place.
- When storing pee, the bladder's walls relax and expand; when emptying urine through the urethra, they contract and flatten.
- The typical healthy adult bladder has a two to five-hour storage capacity of up to two cups of urine.
Three parts of bladder allow urine to be discharged:
- A pair of sphincter muscles. By tightly shutting around the bladder opening like a rubber band, these circular muscles assist prevent urine leakage.
- In the bladder's nerves. When it's time to urinate or empty the bladder, the nerves let the person know.
- Urethra. Urine can travel through this tube and leave the body. Urine leaks from the bladder as a result of the brain's tightening signal to the bladder muscles.
