Hemoglobin inside your red blood cells carries it to your heart, which pumps oxygen-rich blood throughout your body.At the capillaries, oxygen leaves the blood and enters your cells, where mitochondria use it to help produce energy.Meanwhile, carbon dioxide travels back to your lungs and leaves your body when you exhale.One breath.
