The urinary tract is responsible for removing waste fluid from the body. It consists of the bladder, kidneys, ureters and urethra.

The kidneys filter the blood, removes waste and surplus water to form urine. The urine then travels through the ureters and is stored in the bladder until it is ready to pass through the urethra, which is the process better known as urination. The opening of the urethra in men is at the end of the penis. In women it is at the front of the vagina.
