How would you describe the color of blood on the right and left sides of the heart?

• A. Shades of Red
• B. Blue
• C. Green
• D. Purple

Answer: (A)

The color of blood on both sides of the heart is red, though the shade varies with oxygen content. The right side carries deoxygenated blood from the body to the lungs, which is a darker red, while the left side carries oxygenated blood from the lungs to the body, which is a brighter red. Misleading ideas like blue blood come from how veins look under the skin, not from the actual color of blood. So describing them as shades of red best captures the true color on both sides.
