Answer 2

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 through out the body. And it's still red, but darker now, when it rushes home to the heart through the veins.
