What takes the oxygen from your lungs to cells in your body?
A protein called hemoglobin, which is found in red blood cells, carries most of the oxygen in your blood. It does this by having an iron atom at its core that is very good at binding oxygen.
When carrying oxygen, the hemoglobin is bright red. When the oxygen is released, the hemoglobin is dark red and appears blue through your skin.
