Question: Doctor, is my blood really blue inside my body?
Answer: No. Your blood’s always red. When it leaves your heart and travels through your arteries, it’s rich in oxygen, making it very bright in color. After that, it returns to your heart via your veins, but with much less oxygen. This makes it appear darker in color, which can cause your veins to look blue-green, through the filter of your skin. But your blood is still red.
