The Urinary System

The Urinary System is made up of five major parts:

Voiding (Urination)

Normally, when the bladder becomes full (about 1­-2 cups for most people), nerve endings in the bladder wall send a message to the brain via the spinal cord. The brain sends a message back to the bladder to contract the detrusor muscles and relax the sphincter muscles so you can void. If you can't get to a toilet, the brain delays the messages until you are ready to void.
