Circulatory systems Closed circulatory systems: • Blood leaves heart under pressure to arteries then arterioles then capillaries. • Capillaries come in large numbers. They exchange substances between the blood and cells. • After passing through capillaries‚ blood goes back to the heart via veins. • Valves in the veins ensure that blood only flows in one direction.
