messageds[24] = "Circulation
Blood Flows round and round
through blood vessels. This
is called circulation. From the
heart's left side blood passes
into the aorta (main artery),
then into other arteries. Each
artery branches 15 or 20
times, becoming smaller and
smaller. The smallest arteries
lead into anetwork of minute
capillaries.The thin walls of
these capillaries allow oxygen
and nutrients to diffuse
through them from the blood
into the body tissues. In due
course, the capillaries join
other capillaries, eventually
forming veins. These take
blood back to the heart's right
side.This side pumps it to the
lungs to collect more oxygen,
and from there it returns to the
heart's left side. "
