Any time you bleed (and you certainly don't have to open an artery for
that. Surely you've bled in non-life-threatening situations before?),
the hemoglobin in your blood will pick up oxygen from the air and turn
to oxyhemoglobin. That's the red.
If you have a syringe, you can get non-oxygenated blood from a vein-
that's the blueish stuff.
