Quizplus · Accepted Answer

Blood flow from the umbilical vein first flows through the ductus venosus, then through the foramen ovale, and finally through the ductus arteriosus before entering the systemic circulation. This is important to understand in the case of a congenital heart defect, as the abnormality may affect one of these structures and impact fetal circulation.
