Question

Quizplus · Accepted Answer

The ductus venosus bypasses the liver by connecting the umbilical vein to the inferior vena cava, allowing oxygenated blood from the placenta to bypass the liver and flow directly to the fetal heart. The ligamentum arteriosum is a remnant of the ductus arteriosus, which shunts blood away from the lungs in fetal circulation. The foramen ovale is a hole in the interatrial septum that allows blood to flow from the right to the left atrium, bypassing the fetal lungs. The ductus arteriosus connects the pulmonary artery to the descending aorta, shunting blood away from the lungs.
