Every kid should know how the heart works and how take care of their bodies. This entertaining video shows how the chambers of the heart work together as a double pump. Oxygen-rich blood flows from the lungs to the left atrium. Then it is pumped out through the left ventricle to the rest of the body. It returns to the right ventricle and gets pumped into the lungs where it is oxygenated again and the whole process begins again. Fascinating!
