A member asked:

Why is the umbilical cord red and blue in color?

A doctor has provided 1 answer

Blood vessels: There are two arteries-carting oxygenated blood from the placenta and one umbilical vein that carries de-oxygenated blood back to the placenta. The vein is blue and the arteries are reddish in color.
