Difference between menstrual blood and circulating blood?

Question

So I'm just curious.....

Is there any difference between menstrual blood and the blood that circulates through arteries and veins?

Thanks!!

Answer 1

Although blood is from circulation, once blood goes through the menstrual cycle, menstrual blood is different from the regular blood that circulates through arteries and veins, apparently menstrual blood has more stem cells.  For more information on this, please read this link:
