I'm trying to remembeR the differencE from first aids class and I want to say the bright red blood is oxygenated but I'm not sure. Anyhow I've noticed over time that sometimes I'll ht a vein and draw dark blood and using the same vein I'll hit it and it's bright red, or the other way around going from dark to light. I'm pretty sure my bloods travel the same way so what gives here?
