Amniotic fluid is produced by the umbilical cord and surrounds the fetus, providing cushioning and facilitating movement.

The umbilical cord contains one artery and two veins that connect the fetus to the placenta.

The placenta provides oxygen and nutrients to the fetus and removes waste products from the fetus's blood.

The placental bed is where maternal blood and fetal blood mix to provide oxygenated blood to the fetus and get rid of fetal waste.
