Explanation:
Detailed explanation-1: -Blood is always red. Every molecule of hemoglobin-a protein in red blood cells that carries oxygen-contains four atoms of iron, which reflect red light and so give our blood the red color. The shade of red changes depending on the level of oxygen in the blood.
Detailed explanation-2: -The arteries (red) carry oxygen and nutrients away from your heart, to your body’s tissues. The veins (blue) take oxygen-poor blood back to the heart. Arteries begin with the aorta, the large artery leaving the heart. They carry oxygen-rich blood away from the heart to all of the body’s tissues.
