Explain how we breathe. Include the body systems and gases.

We start by breathing O2 through our nose or mouth using the respiratory system. The O2 goes to the lungs and is picked up by RBCs from the circulatory system. The heart pumps RBCs to the rest of the body they drop off O2 and pick up CO2. The RBCs return to the lungs to exhale the CO2.
