Answer to Question 1

ANS: A
As a result, 90 of the blood flow entering the pulmonary artery takes the path of least re-sistance by shunting through the ductus arteriosus and flows to the aorta. Only 10 flows into the lungs.

Answer to Question 2

ANS: C
Figure 9-6 illustrates how the increased O2 affinity is manifested by a leftward shift of the fetal oxyhemoglobin dissociation curve. The P50 (PO2 that saturates 50 of the hemoglobin) is 6 to 8 mm Hg less than adult hemoglobin (HbA), which indicates the degree of the shift toward higher affinity.
