Maybe! Blood is red, and when we’re hot our skin gets pinker because of all the blood near the surface. So if blood was green we’d be greener!
Did you know that scientists have speculated that aliens could have green blood? Our blood is red because it contains iron. If it contained copper it would be greenish. So maybe there’s a planet out there with aliens with green blood?

I guess so! If you look at which bits of your body seem red it’s because there are many blood vessels near the surface of our skin so if our blood was green then I don’t see why not!
Some people have jaundice which is a syndrome where they are more yellow because of something in their blood so technically I don’t see why this couldn’t work for green blood either!

I think if we had green blood our skin would be green! That might be quite cool because wouldn’t we look a bit like aliens then? At the moment we have red blood, which is because our blood contains iron, but if it contained other elements it might be green. Maybe we’ll discover aliens that have different coloured blood! Wouldn’t that be cool?
