- The empty bladder is about the size and shape of a pear and it is located in the lower pelvic cavity.
- The bladder has flexible muscular walls three layers thick.
- As urine fills the bladder, these walls expand; they contract to expel urine.
- The three principal tissue layers of the bladder consists of:
- The three muscularis 'sublayers' are:
- inner longitudinal smooth muscle
- circular smooth muscle
- outer longitudinal smooth muscle
