The Circulatory and Respiratory System When you breathe in, your respiratory system receives fresh oxygen. The oxygen first goes into your lungs and then into the left side of your heart. It is then pumped by the heart into your blood stream. Figure 1.2 shows the flow of oxygen and carbon dioxide pumped to the body. Blood travels throughout your body. The heart pumps blood through a system of large and small pathways that make up the circulatory system. Blood delivers vital nutrients, oxygen, and other chemicals to every cell in your body. Once in the cells, oxygen burns nutrients to make energy.
