How is oxygenated blood supplied to the womb before birth?

Oxygenated maternal blood is delivered to the placenta from branches of the uterine arteries. There is exchange within the placental villi of oxygen and nutrients, when oxygenated maternal blood and nutrients reaches the fetus from the placenta by the umbilical cord, which contains one vein and two arteries. Oxygenated blood and nutrients from the maternal circulation reaches the fetus through the umbilical vein. Deoxygenated or unoxygenated blood pumped by the fetal heart reaches the placenta for re-oxygenation and removal of waste products via the umbilical arteries. The umbilical cord contains two umbilical arteries to carry fetal blood to the placenta and one umbilical vein to carry oxygen-and-nutrient-rich blood from the placenta to the fetus. The ductus venosus allows blood to bypass the immature liver in fetal circulation. The foramen ovale and ductus arteriosus are modifications that permit blood to bypass the lungs in fetal circulation. I hope u got it clearly, does it too dif
