Red blood cells contain a protein called hemoglobin that gives blood its red hue. Hemoglobin contains iron, which makes it an excellent vehicle for transporting oxygen and carbon dioxide. As blood passes through the lungs, oxygen molecules attach to the hemoglobin. When the blood passes through the bodyâs tissue, the hemoglobin releases oxygen to the cells. The empty hemoglobin molecules then bond with the tissueâs carbon dioxide or other waste gasses to transport them away.
