A muscle called the urinary sphincter, located at the junction of the bladder and the urethra must relax at the same time the bladder contracts to expel urine.Īny part of this system can become infected. The urethra is a small tube connecting the bladder with the outside of the body.When the urine reaches a certain level in the bladder, we experience the sensation that we have to void, then the muscle lining the bladder can be voluntarily contracted to expel the urine. The bladder is a small sac-like organ that collects and stores urine.Two ureters, narrow tubes about 10 inches long, drain urine from each kidney into the bladder.Both diabetes and hypertension can cause damage to these organs. Kidneys are also very sensitive to changes in blood sugar levels and blood pressure and electrolyte balance. These functions make them important in the regulation of blood pressure.

The kidneys are a pair of small organs that lie on either side of the spine at about waist level.These are the structures that urine passes through before being eliminated from the body.
