In fetal circulation, what is the role of the ductus venosus? a. connects aorta and pulmonary trunk, thus bypassing pulmonary circulation b. brings oxygen and nutrients to the fetus c. collects blood from veins of the liver and empties into the inferior vena cava d. carries away metabolic wastes and carbon dioxide
Sri K.
Explain the flow of fetal blood from the liver (via the umbilical vein essentially) into the right atrium and through the interatrial septum into the left atrium. Describe how the foramen ovale works by describing some of the other anatomical structures associated with it as part of the fetal interatrial septum. Mixed blood travels to the head and body and back to the placenta via the aorta. The ductus arteriosus connects the aorta with the pulmonary artery, further shunting blood away from the lungs and into the aorta. The foramen ovale allows oxygenated blood in the right atrium to reach the left atrium. Oxygenated blood from the placenta enters the right atrium via the inferior vena cava. Placenta Umbilical vein The ductus venosus shunts oxygenated blood from the placenta away from the non-functional liver and towards the heart. Umbilical artery Umbilical cord (contains umbilical artery and umbilical vein)
