In the fetal heart, oxygenated blood enters through the umbilical vein into the inferior vena cava and proceeds to the right atrium. From there, it passes through the foramen ovale into the left atrium and then to the left ventricle, where it is pumped out through the aorta to the body. The correct sequence is therefore right atrium, foramen ovale, left atrium, followed by the left ventricle, aorta, and ultimately the body's circulation.
