In our bodies, Is are blood red , some say no it's purple?
Question:
Answers:
Truthfully, blood is purplish red in our veins, brighter red in the arteries. Why? The component in our blood which gives it the red color is hemoglobin, which becomes more reddish when exposed to oxygen and less reddish when the oxygen has been removed from it. I've donated more than 9 gallons of whole blood in my life, which is taken from the vein. Believe me, venous blood is indeed closer to purple than red.
whoever told u that blood is purple is a retard
