Human blood is a beautiful red color, but the blood of some animalsâand of humans under certain conditionsâis a different color. The function of all blood is to transport vital substances around the body. Animals may transport some materials in a different way from humans, however. In humans, oxygenated blood is bright red and deoxygenated blood is dark red or maroon. The color is due to the presence of hemoglobin molecules in the red blood cells. Hemoglobin is a respiratory pigment. It transports oxygen to the tissue cells, which need the chemical to produce energy.
