Describe the location of the following with regards to fetal circulation: foramen ovale, ductus arteriosus, ductus venous, umbilical arteries, umbilical veins. What do each of these structures become in the adults? Which of these structures bypasses the fetal liver? Which structures help blood bypass tje fetal lung? Is. lood in tje imbilical arteries oxygenated or deoxygenated?
