Name the 3 fetal shunts and where the circulation occurs.
Ductus Venosus (oxygenated blood travels from the placenta to the fetus through the umbilical cord) Foramen Ovale (blood travels from the inferior vena cava and crosses through a hole within the atrial septum (foramen ovale) into the left atrium) Ductus Arteriosus (blood from the pulmonary veins empties inllto the left atrium and flows into the left ventricle, out the aortic valve, and into the ascending aorta, where it supplies blood with the highest oxygen content to the head) pg 15- 18
