Your urinary system, or urinary tract, produces urine and excretes it from the body.
It includes the kidneys, ureters, bladder, and urethra.
In men, the prostate gland wraps around the urethra at the base of the bladder.
As blood circulates, it passes through the kidneys where wastes and extra fluid are removed to create urine.
The urine then moves down the ureters to be stored in the bladder, an expandable, balloon-shaped muscle.
During urination, urine leaves the bladder through the urethra, and is expelled from the body.
