3. How Does Blood Travel Through Your Heart?

Though the heart is separated into two parts, they work together. The right side gets de-oxygenated blood that has already circulated through your body. It pumps this "used" blood to your lungs, where it is reinfused with oxygen. Then, the blood returns to the left side of the heart to be pumped back throughout your body. The heart has four valves that act as gates, opening and closing to keep the blood flowing in one direction. They work a little like one-way traffic lights. The valves on the right side of the heart are called the tricuspid and pulmonary valves, while the mitral and aortic valves are on the left side.
