I suffered a minor cut this morning and noticed that my blood was real dark. is this somehing to worry about??
Answers: bright red when it is oxygenated and a darker red when it's lacking oxygen.
When oxygen binds to the iron atom in heme, the iron changes its shape slightly, which alters the resonance of the heme molecule. This new resonance gives off a different frequency of light, so the perceived color of the heme goes from dark red to bright red. When the oxygen is released into the tissues, the iron goes back to its original shape, and the heme returns to its normal resonance, so the color goes back from scarlet to maroon. Dark blood will generally come from a vein and carries very little oxygen. Bright red blood will generally come from an artery and is saturated with oxygen
Go to a Dr if your worried
