          why blood is red? Blood is red because it is made up of red cells, often known as red blood cells. However, studying these cells at a molecular level is required to understand why they are red. Hemoglobin is a protein that is found in red blood cells. Hemes, which give blood its reddish color, are made up of subunits of each hemoglobin molecule. IRON MAKES OUR BLOOD RED Hemes (hemoglobin), in particular, have the ability to bind iron molecules, which then bind oxygen. Because of the interaction between iron and oxygen, blood cells are red. (It appears red because of how light is reflected by the chemical interactions between the iron and the oxygen.) And blood's ability to carry oxygen is critical because when blood flows through the lungs, it picks up oxygen and transports it to the rest of the body until the oxygen is depleted, at which point the blood returns to the lungs to obtain more oxygen.
