Answer:
Human blood is red because of the protein hemoglobin, which contains a red-colored compound called heme that's crucial for carrying oxygen through your bloodstream. That's why blood turns bright cherry red when oxygen binds to its iron. Without oxygen connected, blood is a darker red color.
