Urinary bladder is the hollow, muscular, distensible organ of the urogenital system and it is located inferior to the peritoneum. Its main function is to collect urine. The volume of the bladder varies from person to person, but on average, it can hold 400−1000 milliliters of urine. Urine gets accumulated in the urinary bladder where stretch receptors are present. When it gets filled with urine then stretch receptors present in the wall of the urinary bladder send a signal to the central nervous system (CNS) and in return, it stimulates the contraction of smooth muscles of the bladder and relaxation of the urethral sphincter and this causes the discharge of urine. This process is called micturition. But, when stretch receptors are removed from the urinary bladder then also urine continue to form and they are transported by the ureter as usual but now they are not accumulated in the urinary bladder because stretch receptors used to create space for the urine, and hence bladder was able to hold urine for some hours but as now stretch receptors are not present urinary bladder will not hold urine and hence there is a continuous discharge of urine (that means continuous micturition).
