The bladder is layered similar to a balloon with several muscles that make up this organ. It is elastic and can get larger as needed as if fills with urine prior to urination.
When the bladder is stretched it sends a signal through the Nervous System – a parasympathetic response that allows urine to leave the bladder and travel to the urethra. Sphincter control is essential.
Incontinence can be as a result of problems with sphincter control. The bladder is typically sterile – meaning without bacteria
Smooth muscle allows the bladder to enlarge when it becomes full and small when empty.
Overall the bladder can typically hold 400-620 ml but the maximum is twice this amount if the outflow is obstructed.
