The
vascular system consists of the arteries,
capillaries and veins through which blood circulates in the
body. Arteries carry blood away from the heart. The veins
carry blood toward the heart. Capillaries lie in between,
and are minute blood vessels that connect the ends of arteries
with the beginning of veins. Capillaries form networks allowing
blood to be brought into close contact with body tissue;
oxygen and nutrients diffuse from the blood into the tissue,
while waste products diffuse from the tissue into the blood
to be carried away.
