The fetal circulation is characterized by the presence of three physiological vascular shunts — the ductus arteriosus, the foramen ovale and the ductus venosus. Acting in concert, these shunts preferentially stream blood flow in a pattern that maximizes efficiency of blood oxygenation by the materno...
