What could stop the circulatory system from working?
Our circulatory system is dependent on the efficient pumping of blood round our bodies by our four chambered heart. If the heart stops, then the circulatory system will also stop - resulting in death! Blockages in part of our veins and arteries may also cause problems and require treatment.
