In fetal circulation, the lungs are not yet functioning, so blood from the right ventricle bypasses the lungs by flowing through the foramen ovale (a hole in the septum between the right and left atria) and the ductus arteriosus (a temporary vessel connecting the pulmonary artery to the aorta). This allows oxygenated blood from the placenta to circulate through the body without having to pass through the non-functional lungs.
