Answer to Question 1

B
Feedback
A The pressure in the right atrium decreases at birth. It is higher during fetal life.
B With the increase in the blood flow to the left atrium from the lungs, the pressure
is increased, and the foramen ovale is functionally closed.
C Blood flow increases to the left ventricle after birth.
D The hepatic blood flow changes, but that is not the reason for the closure of the
foramen ovale.
