How Your Heart Works - Animation

Your heart is a pump that is responsible for delivering blood to all parts of your body. Arteries carry oxygen-rich blood from the lungs to nourish the cells, and veins transport oxygen-poor blood on its way back to the heart and lungs. This animation shows how the heart and circulatory system work.
