Quick Answer
Hemoglobin is found inside red blood cells in the bloodstream. It is the protein that carries oxygen from the lungs to tissues.
The Full Story
Hemoglobin is located within erythrocytes, the red blood cells circulating through the blood. Each hemoglobin molecule contains iron in heme groups, which bind oxygen reversibly. This allows oxygen to be picked up in the lungs and released in tissues where it is needed. Hemoglobin also helps transport a portion of carbon dioxide back to the lungs.
