The urinary system, also known as the renal system, consists of the kidneys, ureters, bladder, and the urethra. Each kidney consists of millions of functional units called nephrons.
The bladder mechanism consists of the voluntary filling and voiding of the urinary bladder which is controlled by a combined action of the Pelvic Floor muscles (support for the bladder), the Detrusor (muscle surrounding the bladder walls), and the Urethral sphincters (muscles on the Urethra that act as valves for the bladder to be emptied).
