The foramen ovale and ductus arteriosus are fetal structures that shunt blood away from the lungs. The foramen ovale allows blood to flow directly from the right atrium to the left atrium, bypassing the lungs, while the ductus arteriosus connects the pulmonary artery to the aorta, diverting blood away from the pulmonary circulation.
