Why Is Blood Red and Veins Blue?
Most of us have either had our blood drawn or experienced some type of wound where we got to see our crimson red blood firsthand. But what makes blood red in the first place? Medical News Today says it all comes down to chemistry in your red blood cells.
The source explains that red blood cells contain hemoglobin which binds and transports oxygen throughout your body. And your blood gets its bright red color when hemoglobin picks up oxygen in the lungs. So, if our blood is red, why do our veins look blue? The source says it’s actually an illusion. Our veins are white-pink and the blue color “is a combination of the blood, the vessel, the skin, and the process that allows us to see color.”
