Why Human blood is red? |

Answer» Human BLOOD is red because hemoglobin, which is carried in the blood and functions to transport oxygen, is iron-rich and red in color. ... It's BRIGHT red when the arteries CARRY it in its oxygen-rich state throughout the body. And it's still red, but darker now, when it rushes home to the HEART through the veins.Explanation:HOPE IT HELPS YOU!!! |
