Your
urinary tract is the body system involved in the formation and excretion
of
urine.
The kidneys filter out waste products from the blood. These waste products
in
combination
with water are urine. The urine passes out of the kidneys through 2
narrow,
muscular tubes called ureters. The ureters empty the urine into the bladder,
and
the urine is then excreted from the body through a tubelike structure called
the
urethra.
