Urinary bladder collects in the bladder, fed from the two ureters that connect the bladder with the kidneys. Urine leaves the bladder via the urethra, a single muscular tube ending in an opening – the urinary meatus, where it exits the body. Anatomists divide the bladder into:. The apex (prev."vertex") is directed forward toward the upper part of the pubic symphysis, and from there the median umbilical ligament continues upward on the back of the anterior abdominal wall to the umbilicus. The peritoneum is carried by it from the apex on to the abdominal wall to form the middle umbilical fold. The

Urine, excreted by the kidneys, collects in the bladder before disposal by urination (micturition). The urinary bladder usually holds 300-350 ml of urine. As urine accumulates, the rugae flatten and the wall of the bladder thins as it stretches, allowing the bladder to store larger amounts of urine without a significant rise in internal pressure. Urination is controlled by the pontine micturition center in the brainstem. Bacteriuria is the presence of bacteria in the urine which can indicate a urinary
