What is the foramen ovalue?

• between RV and LV that allows aortic circulation during pregnancy

• between RA and LA that allows pulmonary circulation during pregnancy

• allows oxygenated blood in the umbilical vein to bypass the liver

• allows blood from the aorta to go into the pulmonary artery

What is the ductus arteriosus

• between RA and LA that allows blood to cross during pregnancy

• allows blood from the pulmonary trunk to go to the aorta

• between RV and LV that allows blood to cross during pregnancy

• allows oxygenated blood in the umbilical vein to bypass the liver and is essential for normal fetal circulation
