Which property of the urinary tract system allows the bladder to distend with urine while maintaining low intravesical pressures?
Which property of the urinary tract system allows the bladder to distend with urine while maintaining low intravesical pressures?
- The ability of the bladder to contract with enough force and duration to expel all or most of stored urine
- The ability to delay voiding until a socially acceptable time and place are found

How does the lamina propria contribute to normal bladder distensibility?
How does the lamina propria contribute to normal bladder distensibility?
- Secreting signaling molecules that provide input to the brain regarding bladder filling
- Producing elastic fibers that allow the bladder to return to normal shape after voiding
- Secreting signaling molecules that provide input to the brain regarding the need to void
- Allowing smooth muscle cells to stretch slowly without inducing a contraction until emptying is initiated (correct)
