Urinary Bladder

The urinary bladder collects urine excreted by the kidneys.  It is a hollow, expandable structure located in the lower abdomen.   The photo below shows the urinary bladder of a sheep.  The bladder is the balloon-like structure in the upper right area of the tray.   It is still attached to the large intestine.
