Answer: Blood is red because of the hemoglobin inside our red blood cells. Hemoglobin is a complex protein found in red blood cells that contains an iron molecule. Each hemoglobin protein is made up subunits called hemes, which are what give blood its red color. The main function of hemoglobin is to carry oxygen from the lungs to the body tissues, and to exchange the oxygen for carbon dioxide, and then carry the carbon dioxide back to the lungs and where it is exchanged for oxygen.
