In the fetal heart, the blood first enters the right atrium, then passes through the foramen ovale to the left atrium, and from there it is pumped out to the body. This is because the lungs are not functioning in the fetus and do not receive any blood flow. The umbilical arteries carry blood away from the fetus, and the ductus venosus allows oxygenated blood from the placenta to bypass the liver and enter the fetal circulation. The placental artery and ductus arteriosus are not involved in the path of blood in the fetal heart.
