Answer to Question 1

ANS: A
The foramen ovale is an opening in the heart's septum between the right and left atria. The vascular channel between the pulmonary artery and descending aorta is the ductus arteriosus. The channel connecting the umbilical vein to the inferior vena cava is the ductus venosus. The closest thing to a route connecting the heart to the extremities would be the aorta, which then leads to peripheral and cerebral circulation.

Answer to Question 2

ANS: D
The ductus venosus is a vascular channel connecting the umbilical vein to the inferior vena cava. The ductus arteriosus connects the pulmonary artery and descending aorta. The foramen ovale is an opening in the septum between the right and left atria of the heart.
