The urinary System is a group of organs, who’s main function is to filter, store and remove urine (waste) from the body.


There are four parts that make up the Urinary system, they are:

Kidneys

Ureters

Bladder

Urethra

Kidneys  

(Click here to learn more about the kidneys)

The kidneys are two small bean shaped organs, located at back of your body.

This is where the majority of blood filtration occurs in the body. Waste is removed and nutrients are added into the blood.  

Above the kidneys sits two fatty deposits, called the adrenal glands (Click here for more information).  

Ureters

The Ureter is a tube which carries urine from the kidney to the bladder.

Urine passes down the tube, with the help of gravity and several waves of contractions.

The urinary bladder is a muscular sac in the pelvis.

The bladder stores urine, allowing urination to be frequent and voluntary. As urine enters the bladder, it stretches to accommodate. It normally stores 400 to 600 ml of urine.

During urination the bladder contracts and urine passes into the urethra.

Bladder

Urethra

The Urethra is a tube that connects the urinary bladder to the outside of the body.

In males the urethra is a passage for semen during sexual intercourse as well as a passage for urine.

In females the urethra is shorter and emerges above the vaginal opening.
