A. True Due to deoxygenated pulmonary arterial blood passing through the ductus arteriosus to the descending aorta.
B. False The IVC receives oxygenated blood from the placenta.
C. False Deoxygenated SVC blood streams to the right ventricle while oxygenated IVC blood streams via the foramen ovale to the left ventricle.
D. True Since the lungs are not ventilated, oxygen is lost rather than gained in its passage through the fetal lungs.
E. True Umbilical venous blood is only about 80 per cent saturated with oxygen and fetal arterial oxygen levels cannot exceed this; fetal tissues are adapted to survive in relative hypoxia.
