Turning blue?

Post by EmmVeePee » Sat Nov 05, 2005 5:20 am

I'm sure we've all wrapped our finger in a rubber band until it turned purple before... at least I hope it isn't just me.

Anyway, I was explaining blood to some people, and I was telling them that the surrounding tissue of the veins are blue, not the blood itself. They are blue because they aren't getting enough Oxygen from the deoxygenated blood they carry.

Well.. why? How do cells express a lack of Oxygen in blue? Same deal with suffocation and drowning, the victim turns into a blue shade.

Thanks.

I think it's a color that takes emoglobin witohut oxigen; infact metaemoglobin, an emoglobin that for a genetic defect has Eme oxidated, makes peolpe with blue colored faces.
