Urinary system

The urinary system is the body control that controls urine production and urination. It consists of the kidneys, ureters, bladder, and urethra. Urinary symptoms include bladder symptoms, bladder pain, urinary pain, urine retention, and many others. Urinary disorders include kidney disorders, bladder disorders, urinary tract infection (UTI), urinary incontinence, and many others. The medical specialty dealing with the urinary system is “Urology” and the specialist is called a “Urologist”.

Your kidneys make urine by filtering wastes and extra water from your blood. The waste is called urea. Your blood carries it to the kidneys. From the kidneys, urine travels down two thin tubes called ureters to the bladder. The bladder stores urine until you are ready to urinate. It swells into a round shape when it is full and gets smaller when empty. If your urinary system is healthy, your bladder can hold up to 16 ounces (2 cups) of urine comfortably for 2 to 5 hours.
