All VERTEBRATE have two kidneys. Kidneys are
shaped like large reddish-brown beans.
Human kidneys are about the size of a persons
fist. They lie on each side of the backbone,
at just about waist level. Kidneys clean the
BLOOD that circulates the body. They filter
out waste matter and strain off any water
that the body does not need. Blood pumped
from the HEART and flows into each kidney
through an artery. Each Kidney contains
tubes that act as filters. Blood cells,
tiny food particals, and other useful items
stay in the blood to be used by the body.
Filtered blood flows out of the kidney
through veins. All the waste matter and
extra water is mixed together and make urine,
this drips slowly into the bladder.
