How Does Blood Circulate? Lesson Idea
... know that blood flows away from the heart in arteries and back to the heart in veins. Did you wonder why the blood doesn't flow back through the arteries? Explain that the heart has valves. Valves are similar to trapdoors that allow only one-way movement. The valves in each side of the heart keep th ...
