* The bladder is where urine is stored before being expelled by the body through the [[Process of Micturition | micturition reflex]].

==Anatomy==
* It is a hollow, muscular organ

** Caudal neck
** Caudal neck
* Its size and posistion are determined by how full it is.
** When empty the bladder wall is wrinkled and thicker
** When full and distended the folds dissapear and the wall appears thinner
* The paired uteric folds are visible even when the bladder is full.
** They extend from the ureteral opening to the neck of the bladder
** Here they merge
** Forms the urethral crest - continues into the urethra
==The Ligaments of the Bladder==
* Two lateral ligaments
** Insert in the dorsal abdominal wall
** Within them are the residual umbilical vessels
* Median ligament
** Connects the bladder to pelvic floor and linea alba
