Blood from arteries are light red, while blood from veins is dark red. I don't know, but could not 'blue blood' be a term used for deoxygenated blood?

- dhughes 13y agoOr just someone without medical training going by what they see, I mean I look at my veins in my arms and they look blue but I have no idea why that is.
- jeroen94704 13y agoThat's just an optical effect caused by the fact that the veins are (normally at least) underneath the skin. Even oxygen poor blood is not blue.
- dhughes 13y agoYeah I figured something like that. I found this very detailed explanation, in a nutshell skin scatters light. https://www.imt.liu.se/edu/courses/TBMT36/pdf/blue.pdf https://www.imt.liu.se/edu/courses/TBMT36/pdf/blue.pdf And this list of animals with actual blue blood, when its healthy and oxygenated not de-oxygenated: http://www.buzzfeed.com/donnad/10-animals-that-bleed-blue http://www.buzzfeed.com/donnad/10-animals-that-bleed-blue
- Raphmedia 13y agoYou can try a little experiment... Cut a slim slice of ham and put it over something red. See for yourself.
- eitland 13y agoBack in the days where men were made of iron and ships from wood... ... the only people with ski so thin that the veins could be seen through it were the "noble" ones. Looking at their hands it seeemed like they had blue blood. At least that was the explanation of "blue blood" that I got when I was a kid ;-)
