Describe the blood O2 characteristics of the umbilical arteries and veins. How is this different than the normal blood O2 levels in
the arteries and veins after birth?

Expert Solution
Step 1

Umbilical artery- The anterior part of the internal iliac artery gives rise to the umbilical artery and this reaches the placenta by traveling inside the umbilical cord and establishing the circulation in between the mother and fetus.

Umbilical vein- The multiple tributaries give rise to the umbilical vein in the placenta and from there it runs upward from inside the umbilical cord.
