(YOOR-ih-NAYR-ee trakt)
The organs that
make urine and remove it from the body. The
urinary tract is divided into two parts.
The upper urinary tract includes the kidneys and ureters.
The lower urinary tract includes the
bladder and urethra. The kidneys remove waste and extra
fluid from the blood to make urine. The urine flows from
the kidneys through the ureters to the bladder. It is
stored in the bladder until it leaves the body through the
urethra. Also called urinary system.
