Is my blood blue?
No. Your blood is actually red in color when it is oxygenated and blue when it is deoxygenated.
Why does it look blue sometimes?
The veins that carry the blood back to the heart have a much thinner wall than arteries, allowing us to see through them and see the dark, deoxygenated blood inside.
Can I make my blood turn blue?
No, you cannot change the color of your own blood. However, some medical treatments can alter its appearance outside of the body, such as changing its pH level or altering its oxygen levels.
Is there any creature whose natural blood is actually blue?
Yes! Some creatures like some species of octopus, horseshoe crabs and some arthropods have naturally occurring blue-colored hemocyanin in their body as opposed to hemoglobin in humans which gives them their unique blue hue.
Is human blood always red regardless of race or ethnicity?
Yes! Human blood will always be red inside your body regardless if you are Caucasian or African American etc due to the presence of hemoglobin in our veins and arteries that carries oxygen throughout our bodies.
Conclusion:
Despite popular belief, your actual human blood is not naturally blue but rather red when oxygenated and darker when deoxygenated due to light passing through our veins – giving off a bluish hue from certain angles under certain lighting conditions. While some creatures do have naturally occurring blue-colored hemocyanin instead of our own human hemoglobin – this does not apply to humans as our own internal chemistry keeps our bloodstream filled with richly colored red liquid no matter what our outward appearance may be!
